I managed to finally get the old HDD so that I can run the script on it. To my surprise, after being formatted and used (so new files having been written) it found 10 keys, which is about right I guess, I had very few transactions. Sadly, after dumping them to check the balance on them in txt file using your instructions from here: https://bitcointalk.org/index.php?topic=285947.msg3074581#msg3074581

they seem to be on 0 balance on all addresses.

So I guess that's that, even though I find it kind of strange, perhaps it recovered the new wallet Bitcoin Core created after the windows refresh?

I would like you to have a look if you want to, I can send you the initial wallet file I recovered with Icare Data Recovery back in 2014 and from which pywallet extracted 0 addresses and the new wallet created by pywallet (with 10 keys) after scanning the old hard drive. I need your email for it though, I couldn't find it.

Thank you anyway for this program and for your kind assistance so far.

I figured scanning c: would not do anything in this situation but did so anyway just in case.

I'm currently trying to scan the older hdd to it's full size although i assume that since it was formatted and used for storage it is very unlikely to still contain data from 2014.

In case that doesn't work, if you could look at the .dat file i'd appreciate it. Can you link me an email please?

wallet.dat comes from another computer, which windows 7 or 8 at that time "refreshed" (because something went bad and it couldn't boot), which theoretically should've left everything except the system files intact.

When I saw that Bitcoin Core was reset and had started to update from scratch after the windows refresh, I used different recovery programs to find the former wallet. Which I then transferred to another computer that I am using now.

I tried scanning c: and the same thing happens http://imgur.com/a/w2wlC

Thank you for all your help so far an sorry for wasting time with beginner mistakes, I don't know programming.

You example worked, which prompted me to correct the lines i was running to:

python pywallet.py --recover --recov_size 30.1Gio --recov_device c:\python27\wallet.dat --recov_outputdir c:\python27\recover

Which worked but found 0 possible wallets, 0 encrypted keys and 0 unencrypted keys, which I guess means I lost the btc I had there. The only thing that feels off is that the wallet.dat file is 150kb, larger than an empty wallet. I don't remember if I had used a passkey but I think pywallet would've notified me if I did.

I'm doing something wrong because i can't get the program to run.

any command i'm launching only returns the [options] tab. Even if i run --version, it's the same deal.

i tried running

pywallet.py --recover --recovsize 30.1Gio --wallet.dat --recover.dat

pywallet.py --recover --recovsize 30.1Gio --wallet.dat --recover

pywallet.py --recover --recovsize 30.1Gio --wallet.dat --recover.txt

and switching to Mio from Gio.

I tried running the web module and my browser fails to locate localhost.

Thank you for answering. I ultimately managed to get the initial version install, i have no idea how though. I scratched it and installed Winpython as you said. It installed the twisted and ecsda package, however i'm still getting an error i used to get before installing twisted and ecsda:

*ecdsa is installed, if i run python -m pip install ecdsa i get the message that "requirement already satisfied. ecdsa in ...."


tried installing crypto package from here: https://cryptography.io/en/latest/installation/

doesn't solve the problem.


tried installing pycrypto 2.6 as detailed here: https://pypi.python.org/pypi/pycrypto

and i'm getting this error:

tried fixing the chmod error with MinGW https://sourceforge.net/projects/mingw/?source=typ_redirect

also tried fixing this according to this: https://bugs.launchpad.net/pycrypto/+bug/1084871  and this fix: https://github.com/dlitz/pycrypto/commit/68cce56d91a8b96b685d97c937a78b061afbc834


but it's not working


Basically I have no idea what i'm doing.

When i run pywallet.py nothing happens, i can't connect to localhost and i can't run even the simplest of commands like pywallet.py --version

What i need it for is to try recovering a corrupted wallet, so the only lines i'm interested in are --recover and --dumpwallet (i think).

* if i try to run the .bat file it opens cmd and then closes it, localhost can't be accessed by browser.

* tried running everything in d: instead of c: to bypass possible admin limitations, even though i'm logged as admin

I have recovered the wallet.dat file. The problem is it's corrupted and I'm trying ways to open it. Currently trying pywallet but i can't get it to work.

Hello, I'm getting this error when I try to install. I did manage to install it 2 years ago on win 8, but now I am running windows 10.

Can anyone tell me what i'm doing wrong?

I had a laptop with windows 8.1 for about, the OS started bugging out, wouldn't load windows after login screen (black desktop, no apps, no explorer). After several restarts it usually managed to start ok.

I was prompted to run checkdisck, which I did, it discovered a serious error and asked for restart. It tried repairing itself there but was unable to and wouldn't start at all after. I had the option to Refresh and i proceeded, without thinking about losing my bitcoin wallet. Biggest mistake is that i defragged the hdd two times after.

After refresh, i installed bitcoin core client and it prompted me with 0 balance and 3 years to catch back on blockchain (latter is normal i guess). I then panicked and stoped it, thinking i should ask first how to proceed.

It was a modest sum, of about 0.4 btc if i remember correctly, but i would like to know if i can do something to have it back.

I've used Undelete to recover data, i've found a wallet.
Digging further, i've used DeepScan feature to search again and found another entry for wallet, this time in windows.old...appdata\roaming\bitcoin so it appears the file was originally backed up but then deleted (i'm 100% positive i've haven't deleted it). That feature also uncovered many 'wallet' files, but i imagine some are windows related? walletframe.cpp or .h , walletmodel, walletstack etc.

Now i have two wallets, both same size ~152kb, none work when copy-pasted in Bitcoin folder (by replacing the new, empty wallet). I get ”wallet.dat corrupt, salvage failed”

I also tried drag and drop of wallet on blockchain site, nothing happens, not even an error.

I had more addresses on my bitcoin core wallet, the first one being 1UHe24UGtoL6xrzG9YAX3e4zoCu1C9Uca , created on 11 or 12 november 2013, but this is not the address I had the 0.4 btc on. I can't find that one yet but i'm trying to. The address i suspect had the coins I lost is 1KoeNAmguGAc1AgtDqCchwN6wZP8Mg8Xza

Can you please tell me what should I do?

I saw there are some recovery services but I don't know who to trust.

Thank you and have a nice day.

edit: i think I posted in a wrong subtopic. Should I delete this and create a new one or does a mod move it?
