old wallet not working anymore

[fredolin]

In 2013 I had several bitcoins in my wallet.
The wallet is encrypted.

Now, years later, I am trying to bring the wallet back to life.

I installed the actual bitcoin core and I exchanged the wallet.dat with my old wallet.dat.

The blockchain is loading, but suddenly the application hangs with "internal error, see log file for details".
I can restart the client, then it starts again but after some time this happens again.

The logfile says:
------------------------------------------------------------------------------------------------------------------------------------

--------------------------------------------------------------------------------------------------------------------------

I am not able to work with that wallet anymore.

If I use the empty wallet.dat, the complete blockchain loads, but if I am replacing the wallet with the old wallet, this error happens again.
I tried another PC as well, I found no solution.


Any help is appreciated.

Start Bitcoin Core with the -upgradewallet option. See https://achow101.com/2016/07/Bitcoin-Core-Troubleshooting#option-startup for help with that.

[fredolin]

Thank you very much for you answer, but the same is happening again.
It loads several weeks of blockchain.
Then again error.

Try again but with -salvagewallet instead.

Can you also post the entire debug.log?

[fredolin]

salvagewallet doesn't work at all.
Thats the last part of the debug.log. Sorry, but I can see no possibility to add an attachement and the whole debug.log is too much text.

It's failing to add a key to your wallet. Check your permissions on that wallet.dat file and make sure that your user can both read and write to it.

Also check that you have enough disk space and that the drive isn't full.

[fredolin]

Thank you very much for your answers.

I tried -upgradewallet and -salvagewallet.
Same error as described above happens again.

The wallet.dat file was stored on a internet server in 2013 and I moved it back to my computer.
I enabled now this

Same problems again.

The disk is not full.

warner, I will follow your suggestion today evening, thank you.

[achow101]

Did you check the file permissions? It should be under the "security" tab of the properties dialog. You need to make sure that your user account can write to that file.

[fredolin]

I checked the permissions.
The file is not write- or readprotected.

If I write in the console
walletpassphrase ... 300

The answer is:

CWallet::GenerateNewKey(): AddKey failed (code -1)

What do I need to access to this file?

At this point, I am not sure what exactly is wrong and how to fix it. The problem lies in the wallet and Bitcoin Core being unable to write to it.

Can you post the contents of the db.log (not debug.log). There may be something useful in there.

[cr1776]

Before you continue, make a few backups.
>"I checked the permissions. The file is not write- or readprotected."

1. What version of Windows is this?
2. a.If you check permissions for wallet.dat, you said it isn't read or write protected, did you mean it isn't set to "read only" in attributes?  Did you check other permissions?
b. Are you listed as the owner?

2. Do the attributes from the newly created wallet.dat match those of the old one?

[fredolin]

System: Win7
I am listed as the owner

I checked all permissions indicated in the properties window and in the cmd-window (attrib command)

Everything seems ok.


From the db.log:

file wallet.dat has LSN 1/109756, past end of log at 1/333
Commonly caused by moving a database from one database environment
to another without clearing the database LSNs, or by removing all of
the log files from a database environment

So that means that your wallet.dat file is corrupted. That means that while you were moving that file around something got corrupted. Try getting a copy of the file as close to the original from the server.

[fredolin]

Thank you all for your answers.
I was able to save all coins in the wallet.
I installed python 2.7, then extracted all keys with pywallet.py.
This was working somehow.

Then transfered the key to electrum with keys-> sweep.
