installation - Install bitcoin core on raspberry pi 3

How much space left on your local HDD after fresh mynode install - 1TB HD

My machine is linux mint 19.x running virtualbox and nothing else installed. I am at blockheight 573369 running mynode version 0.2.09 and my local disk has 186GB of space left. My virtualbox VM folder inside my home directory has taken up 704GB of space?! I dont understand whats going on here. The bitcoin blockchain itself today is ~270GB. My fresh and minimal install of linux mint combined with this i would expect not to use anymore than ~350GB total for the entire VM but something seems off. I have tried to blow away and reinstall virtualbox/mynode and this keeps happening. Yes, I have turned off and deleted the snapshot function in linux mint as well. The only folder on the entire system that is using up so much space is the Virtualbox VMs folder inside my home directory. Any help would be appreciated!

Guide to getting more FPS. Some simple stuff and random tricks I found to work.

EDIT: IF YOU WERE GETTING THE DXGI.DLL FILE ERROR PLEASE DOWNLOAD RESHADE v3.1.1 HERE http://www.mediafire.com/file/h3b0l50e8dsv8j3/ReShade_Setup_3.1.1.exe AND REINSTALL THEN YOU SHOULD BE ABLE TO USE RESHADE
I decided to make an FPS guide for people struggling to keep their FPS up. There is a ton of stuff you can do to get FPS but the more you do the worse the game will look. It includes simple stuff like editing config files as well as doing stuff like running the game in DirectX10 and dropping your resolution scaling for decent FPS boosts and then using Reshade to get the visual quality back while holding onto the FPS gains. I was able to get about an extra 70-100 fps on average depending on the map doing the stuff below. Here are before and after screenshots:
Here are my computer specs as a reference which is on the higher end with the exception of my videocard (suck a dick bitcoin miners): https://i.imgur.com/TE1whwN.png
Most of the FPS issues with the game stem from how the game is rendering textures so anything you can do to have less and less visible textures the more your FPS will inscrease.
Before you dive into this guide it is probably wise to .zip/.rar any config files you want to save incase you goof something up or just dont like what it looks like.
First, obviously turn everything you can to low in the videosettings. Here is an example of the FPS increase just from having the video settings changed from Ultra to Low.
From here on out all the screenshots will show the FPS with the video settings set to low.
Within your "custom.config" there are a few settings that you can change even though there is no menu option to do so. Your custom config settings can be found at "C:\Program Files (x86)\Steam\steamapps\common\Battalion 1944\Battalion\configs\custom". Here is a link to my current custom.config file:
It may not include EVERYTHING that can be changed since I very well may miss some stuff but it is what I am currently playing with. If you edit this file manually you must maintain the syntax exactly. Things can be added and removed but If you do not have every command in there formatted EXACTLY as "shadowQuality": 0, then your config file will not work and the game will launch with all sorts of fucked up settings.
In the menu settings, just create a new custom.config file (itll show as custom1.config or custom2.config etc within your steamapps\common\Battalion 1944\Battalion\configs\custom folder as im sure most of you know), open it up and then copy/paste my config settings into it. You will have to change your resolution, mouse settings etc. Here are screenshots to show the FPS gains going from stock ultra settings to low settings and now just a few config file edits almost doubling my own FPS:
So that more or less ends the simple .ini/config editing for more FPS. From what I can tell, the Engine.ini and other .ini files can no longer be fully edited to do stuff like increase lodbias and edit lighting/shadows fully to do anything like this https://i.imgur.com/echGUwf.jpg anymore. That config was done entirely by editing the .ini files but alas, I think the devs locked it all up.
If you are REALLY struggling with FPS here are a few tricks that may help you squeeze out a little bit more performance while also increasing visibility depending on the settings you use.
You can force the game to run in DirectX10. Doing so can increase your FPS but also potentially make your game dark as hell. I will address that in a bit.
The FPS increase in training doesnt look like much compared to how fucking awful it may look to some of you but while playing online it maintain your FPS at a higher level due to not fully rendering everything as it would if you run in DirectX11. Especially in busier servers/maps. But as you can see you get even more FPS.
What I have done to counteract the lack of lighting is install Reshade and enable some of the filters to brighten the game up as seen here:
You MUST download and install Reshade version 3.1.1 or earlier. The latest version of Reshade apparently doesnt not work with Battalion. To do this download Reshade here http://www.mediafire.com/file/h3b0l50e8dsv8j3/ReShade_Setup_3.1.1.exe and do the following:
Another thing you can do with Reshade is lower your game resolution or resolution quality to get an FPS boost. It will make your game look like dogshit depending on how low you set it. However you can get clarity and sharpness back through Reshade options. Here are a couple of screenshots of my game with a resolution quality of 75 @ 1920x1080 with Reshade disabled and then enabled.
From the screenshots it may look like there isnt much different in clarity or the game is unplayable but once you join a server I find it to work well. Depending on your system this can be ALL over the place as far as results go but if you tinker with the filters and game settings you should be able to squeeze some more FPS out.
There isnt much more I have been able to find without making the game graphics more or less unplayable. If I can figure out how to edit more .ini comands I will update this post, however I think the devs locked up the majority of the Cvars.
Hope this works for you goobers!
EDIT: Im still working on configs through .ini editing so as I find more stuff Ill update the top this post to reflect the changes.
Testimonials:

Run a 0.14 Full-Node on RaspberryPi3 Pruned(less than 16GB SD needed)

Hi!
Happy if this guide helps you.
Tip if you want: 19656Uwdwko5RjtnuwQENpjBwE3ChzD59v
UPDATE 04/06/17
Add 'uacomment=UASF-SegWit-BIP148' into your bitcoin.conf if you want to signal UASF.
UPDATE 03/13/17
ADDED a tl;dr; Version at the end of this Post.
UPDATE 03/12/17:
Just to test it - I reinstalled all on 8GB SD and it works as well. But maybe you should use at least 16GB for the beginning.
Using a 128GB card for the first version was a little bit stupid - so I reinstalled everything on a 8GB SD card. Including Linux and a pruned blockchain - and it works.
I used prune=550 and Jessie Lite (headless / command line) - without wallet and gui.
The SD is almost full, but it works so far
I also updated the whole manual a bit to make things more clear. Thank you for all your feedback!
Just started my Bitcoin Node today and wanted to share the way I did it with people who are interested in running their own full node. It took some time to write everything down - hopefully correct so far.
I am sure, many people around bitcoin are way more informed and educated as I am - I am the noob. So I wrote this manual to help users like me - noobs, to get started with a cheap, simple bitcoin node on raspberry pi.
Have fun!
I wanted to get my Raspberry Pi 3 working as a node to support the network. Actually the process of installing and running the node was more or less easy - but for Noobs (like I am) it might be a bit tricky to start the whole thing, because there are different ways.
Did you - like me - think you would need +120GB on the raspi, external USB HDD to be a full node? You won't!
If you have a Raspberry and you know what Bitcoin is, I guess, you are a little bit aware of linux, networks and of course bitcoin - so I won't go into detail too much.
This guide is just a little helper to get a full node running on your raspberry pi. Thanks to the help of the nice people in this sub and of course the documentation by the developers, I got it working - and of course also special thanks to raspnode.com - as I followed their tutorial to start - I went some other ways here and there - so please read carefully.
For the Part 2 I would suggest to have http://raspnode.com/diyBitcoin.html open and read through my manual.
I split the tutorial in 2 Parts - PART ONE is about installing the client on your PC and downloading the Blockchain.
PART TWO is about the setup of the raspberryPi and transferring the pruned blockchain to the pi and run it as a full node!
The first thing to be aware of is: You actually need to download the whole blockchain to get this working - if you already have your bitcoin client synced on the PC / MAC great you can reuse it!
Now you might think "but you said less than 16GB in the title!"
Yes, but the good thing is you won't need to download it on your Raspberry, neither you need to sync it completely on your raspberry which took ages (weeks!) before. When you finished this Guide, you will just have a max. 4GB Blockchain on your Raspberry Pi - but it still is a full node! The magic word is Pruning.
Maybe even a 8GB SD Card works just fine including Linux (jessie lite)!
So, if you already have a full node on your PC - Great you can almost skip PART ONE - BUT have at how to Prune in PART ONE if you don't know about it.
For PART TWO you'll need a Raspberry Pi 2 or 3 (I used 3) min. 8GB (works also) or better 16GB SD Card. (I used a 128GB for the first version of this manual - which is way too big)

PART ONE

This is the manual how to get started on you PC / MAC / Linux (I did it on Win7)
Go to: https://bitcoin.org/en/download and download the core Client for your Machine (I used win64).
Install it and configure it to save the Blockchaindata to the directory of your choice - so instead getting 120GB on your C drive, I would suggest to download it to another place like a USB drive.
You can set this up during the install. Standard folder for the blockchain folder is "%APPDATA%\Bitcoin" on Windows.
or you can do it after the install by creating a bitcoin.conf file inside your installation folder / or %APPDATA%\Bitcoin and add
datadir=l:\yourfolder
to the file. Line by line.
By the way here you could also just add dbcache - to use more memory to speed up the process a bit:
dbcache=4096
if you don't want to use the settings inside the program. (you can also set this inside the program under settings! If you have this inside the bitcoin.conf you will see the amount you set there from inside the program - it overrides the values)
You can check inside the windows client under settings, if you can see a manual dbcache is set by having a look at the left footer area. When your dbcache value shows up, everything is fine.
So the Blockchain download process will take time - maybe a few days! Depending on your machine, internet connection and HDD.
The Blockchain is huge as it contains every single transaction of the past until today. You won't need to keep your PC running all the time, you can turn it off and on and it will resync automatically when you start bitcoin-qt.exe!
Make sure to close the client always via "quit" - ctrl+q.
After you have your bitcoin core installed, the blockchain downloaded and synced - you are ready to PRUNE!
First - close the Client and let it close smoothly. After it is really closed you can follow these steps:
By pruning, your blockchain will dramatically shrink. From 120GB to just a few GB.
Be aware, that you will lose your Downloaded Blockchain as pruning will erase a big chunk of it! If you have enough space, you could of course keep the full blockchain saved somewhere on another HDD.
You can prune by editing your bitcoin.conf file by adding:
prune=550
I used prune=1024 - not sure where the differences are right now (min. prune=550). (for my 8GB version I used 550! I suggest to use this.)
Save the bitcoind.conf file and restart your windows client.
It will now clean up the Blockchain. So just the latest blocks are saved. The client should start without any problems. Maybe it takes some time to prune the blockchain data.
Check if everything works normally (the client opens as usual, you can see an empty wallet) than close the client.
Inside the Bitcoin Folder, you'll find two folders called:
blocks chainstate
those are the interesting folders containing the important data (now pruned) - and we will transfer those two to the raspberry later!
Now you are good to start the raspi transfer explained in the next part.

PART 2

Here is what I did:
1) I installed Raspian Pixel (https://www.raspberrypi.org/downloads/raspbian/) using a 128 GB SD - which is not needed because of "Pruning" - I think a 16GB card might work, too! (You can also install Raspian Jessie Lite - which saves you even more space, as it runs headless - only command line) (Updated: It is better to use Jessie Lite to save a lot of space - when you are fine with only command line)
2) I followed partly this tutorial to get everything running and setup:
http://raspnode.com/diyBitcoin.html
Please have a look at it - I have copied the Headlines in capitals to let you know what I did, and what I skipped.
On Tutorial Page: Start with RASPBIAN (OPTIONAL) CONFIG OPTIONS.
Set You RasPi up including "EDITING FILES" to save your Layout at the tutorial page and come back here.
I skipped the CONFIGURE USB AND SET AUTOMOUNT process, as we are going to use PRUNING to reduce the 120GB to a tiny filesize - so USB Devices are not needed here!
It was necessary to ENLARGE SWAP FILE to install bitcoin core - otherwise it didn't went through which ended in a frozen raspi.
So have a close look by following the raspnode tutorial at: ENLARGE SWAP FILE.
I have my raspi running via cable to router - but you can also WiFi setup everything described under NETWORKING ON THE RASPBERRY PI.
Now comes the interesting part: Follow the steps at DOWNLOADING BITCOIN CORE DEPENDENCIES - they work fine for 0.14.0 too. Git should be on Board already when you installed Pixel - otherwise you would need to install it.
sudo apt-get install git -y (only jessy lite)
I skipped the next command lines - as I don't use bitcoin-qt wallet. If you want to use it as wallet - do the step.
mkdir ~/bin cd ~bin
Now you are in the folder you want your bitcoin core data be downloaded to via git. I didn't Downloaded the Berkeley Database source code - so I also skipped the whole next command lines
[email protected]~/bin$ wget http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz [email protected]~/bin$ tar -xzvf db-4.8.30.NC.tar.gz [email protected]~/bin$ cd db-4.8.30.NC/build_unix/ [email protected]~/bin/db-4.8.30.NC/build_unix$ ../dist/configure --enable-cxx [email protected]~/bin/db-4.8.30.NC/build_unix$ make -j4
and went on with "INSTALLING BITCOIN"!
I followed the first part but instead downloading 0.13 I took of course the latest version:0.14
git clone -b 0.14 https://github.com/bitcoin/bitcoin.git cd bitcoin ./autogen.sh
this might take some time to start.
If you have trouble with hanging RESOLVING DELTAS - just restart the Raspberry Pi and remove the bitcoin folder inside /~bin using
rm -rf bitcoin
this command will delete the folder and you can reuse
git clone -b 0.14 https://github.com/bitcoin/bitcoin.git

For some reason RESOLVING DELTAS is a common problem with different downloads - so just retry it and at least after 3 times it should work!

as I didn't use the GUI/ Wallet, I ran
./configure --enable-upnp-default --disable-wallet
as I don't need the wallet functionality.
I didn't need to use "MAKE" which saves you maybe up to 2.5 hours.
instead you can just go ahead with:
sudo make install
(If I am wrong in doing so - please let me know)
The install takes some time - and just a heads up: when it gets stuck somewhere - just redo the installation process - it took three times to went through - stuck at some processing.
After the installation took place you can finally get your Raspberry Pi Node running in no time!
To test if the the installation went through - you can just start bitcoind using:
bitcoind &
than check if everything is working so far:
bitcoin-cli getinfo
after a few seconds you should see version: etc...
if not, something went wrong. Try to redo the steps in the raspnode tutorial.
(don't give up if it failed - retry! Ask your questions here)
IMPORTANT: you need to stop bitcoin on your raspberry now!
bitcoin-cli stop
If you don't need an external USB Drive - what I hope - as we are going to use pruning just go ahead and skip the USB part and create a file inside (or follow the raspnode tutorial on how to setup the USB drive):
cd .bitcoin
sudo nano bitcoin.conf
and enter the exact same pruning size you have used on your Desktop Machine to prune. I used 1024 but the minimum is 550. (used 550 for the 8GB SD card on PC and Raspberry)
prune=550
That's it for the raspi.
update: To signal UASF enter in a new line:
uacomment=UASF-SegWit-BIP148

TRANSFER

Now you have to transfer the two folders CHAINSTATE and BLOCKS from your PC bitcoind directory to your raspberry.
I am using a program called "WINSCP" - it is free and easy to use: https://winscp.net/eng/download.php
We need this to transfer the files to the Raspberry pi. Pretty sure you can also do it via SSH - but I am the noob. So let's keep it simple.
Open Winscp and put in the IP Address of your Raspberry Pi, User and Password (same as in SSH)
You should now see the directories on your Raspberry Pi. There is a folder called
.bitcoin
enter it and you will see the two folders
blocks & chainstate
you can delete them on the raspberry as they have some data from your previous test inside.
Make sure you can also see the bitcoin.conf file in that directory, which needs to contain the exact same prune line, like the one on your desktop machine. If not, make sure to edit it via SSH. The line "datadir=l:\yourfolder" is obviously not needed in the Raspberry bitcoin.conf file.
Now grab the two folders CHAINSTATE and BLOCKS from your PC and copy them to your .bitcoind folder.
I also copied banlist.dat, fee_estimation.dat, mempool.dat and peers.dat to the folder - not really knowing if needed! Not needed.
The whole copy process might take some minutes (against some weeks in the old way).
After copying is finished, you can now start bitcoind on the Raspberry.
bitcoind &
the & symbol let you still use the command line while the process is running btw.
The process - if succesfull - will take some time to finish.
bitcoin-cli getinfo
Will give you some informations what is going on right now. When you can see, that it is checking the blocks, this is good!
If you get an error - double check - if you have the correct prune size (same as on desktop machine) - in bitcoin.conf and that this file is inside .bitcoin on RaspberryPi. It took me some time, to find my mistakes.
Congrats! You are almost a part of the network!
To make your node now a fullnode, you will need to go to your router (often 192.168.1.1) and enable portforwarding for your raspberry pi - and open ports 8333 - that's it!
You can now go to: https://bitnodes.21.co/nodes/
scroll down to "JOIN THE NETWORK" and check check if your node IP is connected!
It will show up as soon as the blocks are checked and the raspi is running.
Well done!
Now you are running a full node, with a small Blockchain and got it working in Minutes, not weeks!
I really hope, my little tutorial worked for you and your are part of the Node network now.
If you have problems or I made a mistake in this helper tut, just let me know and I will try to make it better.
Have fun and NODL!
the noob
tl;dr; (if you are a real noob start with the non-tl;dr version!)
tl;dr; PART ONE
1) Download & install / setup bitcoincore @ https://bitcoin.org/de/download
2) change dbcache to something smaller than your memory and download the whole Blockchain (120GB).
3) create a file called bitcoin.conf put the line prune=550 (or higher) in to activate pruning on win inside %appData%/bitcoin
4) Open ports 8333 on your Router to make this a full node with a smaller Blockchain.
You are running a full node on your PC.
tl;dr; PART TWO
1) Install jessie lite and the needed dependencies on your SDCard - Raspberry
( >git clone -b 0.14 https://github.com/bitcoin/bitcoin.git )
  • see tutorial for more info.
2) create a file called bitcoin.conf inside .bitcoin and add the same prune=Number you had on your PC.
3) transfer the pruned folders BLOCKS and CHAINSTATE to the Raspberry Folder .bitcoin
4)Start "bitcoind &"
5) let everything sync
6) Make sure you have port 8333 opened on your router.
You are running a full node on your Raspberry with a super small Blockchain (I put all on a 8GB SDcard)

Move entire Bitcoin core directory to new drive

Hi!
I currently have 0.52 BTC in my Bitcoin Core wallet on my desktop PC. I am installing a new processor tomorrow and will be doing a Windows reinstall.
My wallet.dat is encryptet and backed up multiple places.
My question is: Would it be best to copy the entire Bitcoin Core directory, or just the wallet.dat file onto the new install?
Many thanks for any answers.

The curious case of trezord's "pgdata" ownership

I own a TREZOR bitcoin hardware wallet, having purchased and set it up last year. I haven't really used it since then, but I installed the Trezor Bridge software on Ubuntu 16.04 LTS to make it usable with the website for configuration. This all went smoothly, and I was overall happy with my purchase. That's not exactly what this post is about.
It has been months since I last used the Trezor. Tonight, I was doing some things related to my day job -- for those in the world of web apps (everyone else might be confused), I was dockerizing a new application and setting it up to be used with Docker Compose, specifically configuring a database container for it. For many of the applications I've dockerized, I keep a local directory inside the repo's directory called pgdata. This is the name for the directory where the data of a Postgresql database will be stored. I use these local pgdata directories to mount into a Postgresql Docker container for development purposes. This is all rather mundane and uninteresting on its own, but here it gets a little odd.
Tonight I was creating another such directory for this new app. To remember how I had configured the other directories in the other repos (permissions and such), I went to go look at one of them as an example. All looks fairly normal until I ls -laF one and see:
drwx------ 19 trezord root 4096 Jul 20 2016 /home/username/repos/appname/pgdata
Wait... what? Why is that directory owned by a user name trezord? Who is trezord? I recalled immediately installing Trezor software, and did a quick command to find out if this was related:
$ cat /etc/passwd |grep trezord
trezord:x:999:998:TREZOR Bridge:/var:/sbin/nologin
And of course a process check:
$ ps -ef|grep trezord
trezord 1339 1 0 18:17 ? 00:00:00 /usbin/trezord -f
Okay, sure, this is the user for the Trezor bridge daemon. But why did it own this directory? I wasn't even aware this user existed, so there's certainly no way that I changed ownership of these directories. I'm open to the possibility that I made some kind of mistake, but that seems like it would be one of the most strange mistakes I'd ever made, considering I'm sure I lacked the knowledge normally needed to make it.
I had to see if this was an isolated case, so I went ahead and ran this command to see who the owner of all of the other pgdata directories was:
sudo find / -name pgdata |xargs sudo ls -ld
It came back with all the directories named pgdata on my system, all for different apps (many of which I haven't touched in some time). Do you want to guess who owned them? That's right, trezord owned all of them. More than a little odd, I'd say.
I looked for any references to postgresql or pgdata in Trezor's repos on Github and couldn't find any. I tried restoring proper ownership of the directories, uninstalling and reinstalling the Trezor bridge just now to see if anything would happen (I didn't really expect anything to). Nothing has, yet.
All in all, I'm having a strange, strange night. I have some of my own rather undeveloped thoughts (hint: paranoia) about what could have gone on to cause this situation, but I'd like to do more research before I make any claims. Meanwhile, I'd like to hear whether anyone here -- and especially TREZOR devs -- have any ideas about this. Is there any means by which you can imagine the trezord user wanting or taking ownership of directories by that name? Do you think it's more likely I made some sort of outlandish blunder that I simply don't recall? I personally can't see why I would have executed a recursive chown against all directories by that name, or why in the world to that user either. I'm starting to question my own sanity here.
Hopefully I just did something on my own to cause this. Things are a little more concerning if I didn't. Advice is appreciated.
Edit: stickac had it! See the comment.

Having a problem installing ABC node on my Mac

Hi, I posted this on btc as well but haven't found a solution yet. I'm trying to get a node running on my Mac before going out of town tomorrow but ran into the issue described below:
During setup, I set the drive used to save the blockchain but accidentally selected the wrong one and it began to sync to the incorrect drive. I was forced to send the app to the trash and then empty it. I reinstalled it and when I opened it, it just picked up from where it was syncing from before to this same incorrect drive.
I found where I was able to pause the sync and go to preferences/settings to reset settings. This allowed me to select the proper drive, but now its saying "Cannot obtain a lock on data directory /Volumes/G-DRIVE USB. Bitcoin ABC is probably already running. No such file or directory." where G-Drive is the correct drive that I'm trying to save to.
I have tried deleting it and reinstalling, but when opening the app it just throws up this same error and closes out. I also have tried finding the Bitcoin.conf file as well as its application support directory but neither seem to exist. Is there still a process running in the background from the previous install that is potentially causing issues? Or maybe some sort of registry file on the machine that inputs the previous settings even on a fresh install? Lastly, why does access to my external hard drive seem to be blocked?
This is also the drive that I use as my Time Machine backup if that matters.
edit: typos

recover bitcoins? longish post sorry

I am very uneducated with crypto, but work in the IT field and understand PC software/hardware well.
Back in february or so when eth was booming, I had a GTX1070 and saw the massive rise from what I paid in its price, so I listed it on ebay. During the week I had it listed, I mined ETH for a pool and was paid in bitcoin.
I only made 0.008 BTC, around 15 bucks at the time, had it stored on I believe a bitcoin core client on a hard drive.
after I stopped mining, I figured what the hell, 15 bucks ill leave it in there. Flash forward to now, and its a little chunk of money I would rather not lose(no harm done if I do though).
I built a new PC in september, using new drives, and threw the old drives on a shelf. Now after trying to figure out where my bitcoin pieces are, I cant seem to find anything in any of the bitcoin core applications I had used, though I know I got paid out for sure as my wallet was updated at one point months ago and showed my balance.
I have like 4 different wallet.dat files from backups/attempts to reinstall but everytime I select the directory for bitcoin core and install/wait the 8years 3weeks or whatever it says, it finishes and I have 0 balance, Have tried with multiple directories in multiple drives, maybe I am not recoverying the wallet correctly? the other 50% of the time Ive tried to install from a directory I get an error saying the directory is corrupted or damaged and it doesnt even install the program.
Is my wallet information all stored in wallet.dat and if I have all of those, should I have a way to recover it and if so how?
I just simply want to transfer my bitcoin pieces to a phone app or the sort that use the 12 word key recovery so as to not lose everything so easily.
Im not asking you guys to spend a bunch of time doing my research, but if you know of anywhere I can find articles or something how to go about recovering this.

Bitcoin ABC installation help

I'm attempting to install BitcoinABC to my mac to run a full node. When I tried to set the drive used to save the blockchain, I accidently selected the wrong one and it began to sync. I was forced to send the app to the trash and then empty it. I reinstalled it and when I opened it, it just picked up from where it was syncing from before to this same incorrect drive.
I found where I was able to pause the sync and go to preferences/settings to reset the settings. This allowed me to select the proper drive, but now its saying "Cannot obtain a lock on data directory /Volumes/G-DRIVE USB. Bitcoin ABC is probably already running. No such file or directory." where G-Drive is the correct drive that I'm trying to save to. Is there still a process running in the background from the previous install that is potentially blocking me from switching drives?
This is also the drive that I use as my Time Machine backup if that matters.

How to back up Blockchain for new Bitcoin Core install

I'll be reinstalling Windows 10 on a new system (motherboard) soon and need to move my Bitcoin Core client over as well. I don't want to redownload the whole blockchain. Is it as simple as just copying the "blocks" folder from the %AppData%/Roaming/Bitcoin directory and replacing after installing Core again?

So I'm really stupid.

Eve hasn't been working for over a week. I would launch the client and it would crash before even giving me a login screen. I tried all the usual stuff, clearing cache, reinstalling, uninstalling with Revo Uninstaller, even resetting my drivers with guru3d's driver sweeper. CCleaner, Ncleaner, Windows updates. I might get as far as the EULA and crash after clicking accept if my cache was recently cleared, or get to a login box but crash after mousing over it.
On what I thought was an unrelated note, Heaven & Hearth, a java game, was also crashing regularly. I didn't really draw a connection between these two things.
I work at a local computer repair store. It's what I do eight hours a day, so when I come home from fighting with Security Tool 2012 and 2012 toolbars all day, and recovering the ex Grand Dragon of the KKK's Incredimail profile (I am not joking) after a particularly nasty virus, I really don't feel like diagnosing my own bullshit. So instead I just get drunk.
And belligerent.
It doesn't help matters that Acronis Drive Monitor started throwing SMART errors on the last PATA drive I had installed (some legacy gear left over after I ran out of money on a new gaming rig, I threw in some old drives I had laying around), so I brought a new SATA home from work to image it to and replace it with Paragon. I thought the errors were due to the failing drive, an honest mistake I think. I continued to chalk up the errors to the drive, after the drive was gone, thinking likely something got either corrupted during failure, or during the clone.
I file a petition and quickly escalate up to "level two techs" once they can see I know what I'm doing (...lol) and forward them a few crash logs, dxdiag log, ran memtest86 over night just to be sure, etc etc.
By the way, these guys are great. Above and beyond the call of duty. Did I mention my drunken belligerency? I had no patience -- and made sure to let them know -- for paying good money for DurrHurrDurr Online: A Bad Game and not even being able to flip skills while Winning at Eve, while paying for it. I really need to learn not to email while drunk.
In a moment of clarity (I ran out of rum), I realized something.
I'm a digital hoarder, you see. I have four browsers installed. Chrome, Iron (a fork of Chromium), Firefox, and Opera. I have them all installed because I'll have 200 tabs open (that's without hyperbole) because I'll get it in my head to reinstall VtM Bloodlines in an act of symbolic defiance against the Twilight generation, and of course I need to download recent patches, and mods, and texture packs, and this and that. And they all have to be installed in a certain order. So there's 15 tabs right there to just that task. Then I notice it's 3:30 in the morning and I have work in a few hours. So I minimize the browser, put some Joy of Painting in a random playlist to get my ASMR on so I can hate the world less, and go to sleep. Next day, when I get home from work, maybe I'm not in the mood to play Bloodlines anymore, because I saw someone on Reddit mention OpenRA. So there's an other ten tabs.
See where this is going? And if I need to reboot? My brain is full of fuck. That means when I reopen my browser to check something quick later, I have to wait for 200 tabs to open. Why don't you just book mark them? Because I need them organized in a certain order, the order, say, mods for whatever need to be installed in. (But more than likely it's 25 tabs of tvtropes. I'm a terrible person.)
To make a long story short (I think we're well past that), I have four browsers installed, each with 200 tabs open, and I just want to check one thing real quick.
Like, for example... reactivate my Eve account. Which hasn't worked since I reactivated it. How did I reactivate my account without loading 200 tabs.... What... browser am I currently running... while I drunkenly make my 8th reply to this petition....
ಠ_ಠ
Oh god.
I'm running Internet Explorer. I've been running it for over a week. And I'm not running any anti-virus software. Because I "know what I'm doing."
"It will be okay, it'll be quick, in and out, I'm only going to one site... Well, lets see what's on gonewild... ohh that's nice..."
So I quickly pull out my work flash drive, browse to the triage directory where I keep all my tools, roll my selves up, and "go to work", pretending that this is an other grandma's computer... with a $700 video card in it. More rum... why is the rum always gone...
Combofix dumps a log that I never expected to see on my own computer. Briefly:
((((((((((((((((((((((((((((((((((((((( Other Deletions ))))))))))))))))))))))))))))))))))))))))))))))))) . . c:\program files (x86)\INSTALL.LOG c:\programdata\xmlC203.tmp c:\programdata\xmlC5EC.tmp c:\programdata\xmlC7A3.tmp c:\users\Cronyx\AppData\Roaming\Bitcoin c:\windows\jestertb.dll c:\windows\pkunzip.pif c:\windows\pkzip.pif c:\windows\system32\java.exe c:\windows\SysWow64\Config.cfg e:\$recycle.bin\S-1-5-21-3258354944-3994639180-3281853217-1012\$RWOXBZL\jestertb.dll
Good lord. A few more passes with other tools later, and she's clean. I reboot and reinstall Java and my video drivers, again. Reset the MBR for good measure to kill any traces of rootkits.
Run repair.exe.... After a few minor updates, Eve's checksum clears, all green.
Double click that blue E... NO NOT THAT ONE! There we go...
Aura, it's been so long... how I've missed your voice. Yessss.
A few weeks ago, a guy came into the shop and asked if we were hiring. He claimed that he really knew what he was doing. He dropped a lot of technical verbiage -- hyper spanner, dilithium crystal, Geordi Laforge -- that he was very confident were in the right order, with associated adjectives and punctuation. He didn't quite sputter out sentence fragments and light things on fire, but after warping up and offering to take a resume, but we didn't have any positions available right now, but you never know later, etc etc, on his way out, he mentions that his Internet Explorer is broken and won't go online. ಠ_ಠ
To GM Haggis, and GM Retrofire, you are truly gods among men and examples of why CCP has the best customer service in the industry. I sincerely apologize for wasting your time and being that guy.
True story.

Deleted profile, Waterfox no longer works. Please help.

Hello,
I've been dealing with this problem for some time. I gave up trying many months ago and decided to just use Chrome, but man, it performs so poorly, I really want Waterfox back.
I got infected with a BitCoin miner and long story short, I believed that the miner was hidden inside of the directory used for my Waterfox profile. I deleted the entire directory, and Waterfox has not worked since.
To be specific, Waterfox launches and opens just fine. It can even display the default home page. The problem is that it can not go to any websites. I type a site into the address bar and hit Enter, and it sits there and does absolutely nothing. It quickly looks something up, shows the reload icon as if the page has loaded, and clears all text from the address bar. Attempting to reach a site via a bookmark does the same thing. I get no errors. Just nothing.
It doesn't matter that I've installed / reinstalled Waterfox numerous times, it always does this. I tried the portable version, this still happens. I've just about run out of ideas.

PSA: Added Step May Be Needed When Restoring a Backup Encrypted wallet.dat to Bitcoin Core

TL;DR: To successfully restore an encrypted wallet.dat file, the instance of Bitcoin Core getting restored to needs to first have Encryption turned on and possibly the same Passphrase set as the wallet.dat file you are restoring. It seems this must be done before you restore your encrypted wallet.dat from backup, or Bitcoin Core will just show a zero balance.
For the record, the set-up for this situation was as follows: Bitcoin Core (formerly Bitcoin-Qt) 0.9.2.1, Windows x86 version, on Windows XP Pro patched for 2019 PoS updates.
Recently, my Bitcoin Core hot wallet had been acting up and crashing after about 6 to 12 hours of uptime. I thought that there was possibly some corruption in Core's database files, so I backed up my wallet.dat and started deleting block chain data/index files to see if a rescan or reindex would correct the problem. I tried to save time by not deleting everything, only certain file types. I managed to somehow screw up and got the dreaded "wallet.dat corrupt, salvage failed" message.
Since I had a backup, I didn't bother trying the "-salvagewallet" command-line option (which might have actually corrected my problem.) Instead, I went straight for a restore from backup.
Some time ago, and on a much older version of Bitcoin-Qt I had familiarized myself with the wallet.dat backup and restore process. I never had a problem with it. But thinking back, I may have done all of my testing with unencrypted wallet.dat files.
In this case, I uninstalled Core, deleted everything in the Bitcoin data directory, reinstalled Core, used bootstrap.dat to catch up as much of the block chain as possible, and let the new install finish syncing from the Internet. Once Core was up-to-date, I closed it and restored my encrypted wallet.dat from backup.
In my previous experience, I'd be done at this point. The next time I started the wallet, it would have automatically rescanned, and I'd be back in business. This time, when the wallet finally started up again, it showed no errors, the block chain was still fully synced up, but the wallet showed a zero balance. Not a good feeling.
I thought maybe I'd need to manually start Core using the "-rescan" command-line option. I tried this, but got the same result.
After mulling things over, I finally guessed that the problem might have something to do with Core's wallet.dat encryption.
I again deleted the wallet.dat file from the Bitcoin data directory and restarted Core. Once it finished generating a new wallet.dat file, I enabled Encryption and set the same Passphrase as the wallet.dat file I was trying to restore. Core shut itself down to complete encrypting the new wallet.dat file. Next, I started Core once again to make sure all was OK with new encrypted but empty wallet.dat. I then closed Core and replaced the zero-balance wallet.dat file with my recent backup. That finally did the trick. On the next start, Core automatically did a rescan and my balance reappeared.
I don't know for sure if this behavior is the same across all the different flavors of Bitcoin Core 0.9.2.1 (x64, OSX, Linux), but I suspect it might be. Also, it might work just to enable Encryption, but it might not be necessary to have the same Passphrase. I can only confirm that it worked in my case with the same Passphrase.
This little adventure was unnerving, particularly since Core issues no errors and just insists there's a zero balance. I thought I should relate what I learned in case someone else encounters the same situation.
Cheers, and to the moon!
EDIT: At least a couple posts so far report not seeing the same behavior I did. I'm glad if it's a non-issue, and I can't explain why it happened to me. I can just suggest if you have similar issues, it might be worth it to give this method a try.

[Question] Importing Wallet.dat?

I have the wallet.dat file from my desktop (I backed up the whole Bitcoin directory before reinstalling). I want to import all of its addresses and keys into the Bitcoin installation on my laptop. How can I do this? I imagine "cat" is not the utility of choice.

My privacy practices....

I am a bit of a privacy nut. Not too drastic, but I don't like being tracked online. Its nobody's business as far as I'm concerned.
Here's what I did recently:

Now you can earn money and browse the webs and stuff anonymously.
I never reveal any personal information when browsing. Its absolute freedom to use tor.

help with possibility of recovering wallet.dat

I'm going to preface this post by saying that I'm pretty sure I've made a stupid mistake that will probably result in a relatively inexpensive lesson. But here's what I did:
I run my C: off a 160gb SSD. I also have doge and bitcoin wallets installed on this C:. I noticed that I was quickly running out of free space and also noticed that the combined downloads from btc/doge were over 30gb on my HDD. Then, in my infinite wisdom, I decided to delete both directories. The doge one went to the recycling bin, and the bitcoin one was deleted straight up because it was too large for the recycling bin.
It wasn't until later when I reinstalled both wallets that 1) changing the install directory of the wallets doesn't change where the blockchain gets downloaded to, and 2) I forgot to make a backup of my bitcoin wallet.
I was, fortunately, smart enough to save a backup of the doge wallet. But now that I've reinstalled my bitcoin wallet, I have new files where the old ones used to be, and I can't seem to have any luck restoring the old files through the free file utilities. Anyone have any ideas?
I actually had most of my wallet saved on blockchain.info's online wallet, but a couple days ago I created some new addresses to take a 0.1btc payment. I have the public addresses for the payments but can't figure out how to link them to my blockchain wallet without wallet.dat. Any help would be appreciated, and sorry for the wall of text!
