Corrupted wallet.dat - any way of repairing?

[frotto]

Hi everybody, my SSD crashed today, and of course, I hadn't made a backup of my wallet.dat file. I managed to restore the file, but when I launch bitcoin, it gives me a '11DbException' error message and then closes itself. Is there any way of restoring the file? I do have the address, just can not access it.

Ouch! Yea having the address won't help much. There is bitcointools and IIRC there was another wallet dump/export utility mentioned somewhere on the forums here. Play around with bitcointools and see if you can get anything out of your wallet.dat.

Did you delete all other files in the data directory before restoring wallet.dat? Maybe those files are corrupted.

Yes, I did try that, didn't help.

Try running dbdump.py --wallet --datadir=/path/to/corrupt/wallet/ from bitcointools, if you get a reasonable looking data, you might be ok, otherwise well you might try some more advanced BDB recovery tools.

Could you please give me a step by step guide how to do this? I'm useless when it comes to python. Thanks!

Code:

# git clone https://github.com/gavinandresen/bitcointools.git
# cd bitcointools
# ./dbdump.py --wallet --datadir=/point/to/wallet/dir

Use ./dbdump.py --help for other options.

# git clone https://github.com/gavinandresen/bitcointools.git
# cd bitcointools
# ./dbdump.py --wallet --datadir=/point/to/wallet/dir

Use ./dbdump.py --help for other options.

I still wasn't able to figure out what to do with these commands. I tried putting them in the python command line, but it did absolutely nothing. Again, I haven't ever worked with python, so any help would be appreciated!

How many bitcoins did it contain?
How many bitcoins would you offer for me to repair it? (only if succesfull)

I'd be willing to send you some bitcoins (3-5) if you help me repair it.

You know he could just keep it himself, right?

Yeah, well, I would still end up with nothing.
I would really like some help with the repairing, though :/

I'll help, pm me.

I was able to get it working and ran it, but the program (dbdump.py) just says "Couldn't open wallet.dat/main, try quitting Bitcoin and running this again." Even tried fixwallet.py, but same result. I guess I just lost 20 BTC.

Was bitcoin still running when you tried the dump?

[frotto]

Was bitcoin still running when you tried the dump?

No it wasn't, I'm not that stupid I did this on a virtual computer running Ubuntu Live CD.

I have a few hidden tricks up my sleeve for repairing corrupted wallets, but they're time consuming, so if you want I can try

I wouldn't mind taking a look too.
