Whatever the cause, im done with Bitcoin QT. And any software for storage. Paper wallet until something significantly more stable comes out.
Unless they want to start providing people with their private key information, which continues to astound me (that they dont).
When you've got a shit ton of money stored in some software that won't even tell you your own private key, and routinely has bugs/failures/errors ... you'd have to be insane to put your money in it.

Just an update to this, i figured out (thank god) a way around this.

1) When I move my wallet.dat file offline to a storage device, I copy the file, then paste it to the new location, then renamed it to another xxxx.dat
2) I then delete the wallet.dat file I copied.
3) When I moved the wallet.dat file from the offline storage back into QT directory, it failed to open.
4) When I pulled the deleted wallet.dat file from recycle bin, it opened, and as fast as a possibly could, I moved all my coins out of QT to a paper wallet.

Apparently the act of moving the file and/or renaming it and moving it back ... causes corruption in the file.

This was the only solution that worked.

are you kidding?

to view your privatekey type the following into the console.

Code:

ERROR:root:Couldn't open wallet.dat/main

This usually happens when you don't (correctly) use the parameters --datadir and --wallet to tell pywallet where your wallet is.

No I specified the 'datadir' and the wallet was still named 'wallet.dat' and it said that it defaults to that -- I guess I could try again specifying the 'wallet.dat' as the name?

try importing the wallet on a windows or linux computer and fixing with pywallet. its worth a shot.

just got the latest pywallet (2.1.6) from Github, and tried it in Ubuntu 12.04 LTS w/ all the packages installed ... same error:

Code:

You hit a common easily repaired issue and, unfortunately, made it worse. ::sigh:: Nothing unrecoverable, most likely. Whoever told you to do that, please go punch them in the face.

I have backups of the __db.XXX files - and the wallet.dat files from when the original corruption occured.

And I followed instructions here : https://bitcointalksearch.org/topic/guide-simple-wallet-recovery-using-bitcointools-11331

They seemed to make logical sense, but I guess they were wrong -

I attempted to run it with `fixwallet.py` as mentioned.

Deleted everything except 'wallet.dat', and reopened Bitcoin-Qt (Also tried this after downloading 0.8.1), not the same result, instead of a crash I get: 'wallet corrupt, salvage failed' message when launching, the wallet.dat file is replaced with a 'walletxxx.backup'

By doing this you corrupted your wallet. When the software is not cleanly shut down the wallet file may be in an inconsistent state and it many need the database/ subdirectory in order to be read— but you deleted that.

It refuses to go further now in order to avoid risking damaging more data.

You hit a common easily repaired issue and, unfortunately, made it worse. ::sigh:: Nothing unrecoverable, most likely. Whoever told you to do that, please go punch them in the face.

First, The standard question:

Do you have a recent backup? If you have a recent backup the easiest path to recover will just be to use that.

Secondly, the important initial advice:

Before doing anything else, make a new backup of your current wallet.dat (and the database/ subdirectory if there is one anymore) and don't overwrite any old backups.

Just happened to me too.

I love how fucking buggy this software is. given that it has entire savings accounts in it.

Who are the programmers? Do they give a shit? What if you have $10,000 worth of BTC in the file? "Tough luck" ?

No support? Nobody replies? Thread just goes dead?

This is bullshit. You can't have "bugs" and amateurish bullshit software when people's life savings are at stake.

What's the solution to this new bug? I am never trusting my wallets to Bitcoin QT again. I haven't seen this many fucking bugs since windows 3.1

What version of the Bitcoin-Qt are you on?

I tried to launch the wallet file against 0.8.5 and got the same "wallet salvage failed" error again, so that hasn't helped things.

I guess I'd recommend a hosted wallet like "blockchain.info" - there are lots of other non-hosted implementations of Bitcoin you might consider if your disappointed with the bitcoind / bitcoin-qt software.

Here is the most recent log:

So, I downloaded Bitcoin-Qt v0.8.2 and the wallet.dat file from my backup consistently returns the same "wallet corrupted" error.

I've also pulled the latest development branch off Github, and have built Bitcoind and directed it to run with the --datadir of my backup wallet, same result

Code:

macbook-pro:src jordanbaucke$ ./bitcoind --datadir=/Users/jordanbaucke/Library/Application\ Support/BitcoinBK/ -listen=0
Error: wallet.dat corrupt, salvage failed

Also the back-up files (a new one is created in the current directory whenever I launch the client with the corrupted wallet.dat) from the backed-up original directory don't work either (probably from attempts to launch with that directory)

I'm imagining if I had more BTC in this wallet and what sort of sick feeling that would give me, so I'm hoping that there is a tool out there that will let me explore this issue deeper and discover the problem?

Anyone?

I'm having the exact same issue, I also tried importing the wallet.dat into blockchain.info and that didn't happen, but the backup wallet from a previous version of bitcoin-qt worked.

I never had any luck restoring. I tried a few different tools like pywallet ... no luck

Hi
Interested in this thread as i'm getting the occasional crash (ML 10.8.3 - Mac Mini 16gb Ram)

I'm guessing i'll need to remove -> re-install and place wallet.dat in correct directory then launch?

Cheers

Not sure if this will help you but:

I had exactly the same on Linux when I did a fresh install. Fixed it by: Deleting wallet.dat, run bitcoin-qt (in my case: 0.8.1-beta), it will create a new wallet.dat, shut down bitcoin-qt (it takes a while, so wait), overwrite newly created wallet.dat with the one from the backup, restart bitcoin-qt -> worked for me

no joy yet, the program didn't crash, but I got a "wallet corrupted - salvage failed" again - anyone else have any other suggestions?

Update

Looks like I'm not the only one having issues with wallet corruption w/ OS X 10.8.3 on a Macbook Pro (or something similar), see here: https://github.com/bitcoin/bitcoin/issues/2435

Some are prompted to "redownload the block chain" though I haven't gotten this. After reinstall 0.8.0-beta and replacing the file here is are my log files:

I went to open Bitcoin-Qt 0.8.0-beta, which I have been running for about a month, earlier this weekend, and discovered it was crashing when opening in OS X Mountain Lion (10.8.3) and after I few tries attempting to get it to open, I figured I must need to fix my wallet file, or upgrade Bitcoin-Qt, but nothing has solved it so far.

I'm not extremely concerned as there wasn't much coin in there, but what I am concerned about is the fact that I haven't been regularly backing up my wallet.dat file that I keep locally (I know I should) but it's mostly a staging area when I move coins between some online places.

Here is the output of the Apple crash report:

I followed all the usual procedures after creating a complete copy of my Bitcoin folder (~/Library/Application Support/Bitcoin)

Deleted everything except 'wallet.dat', and reopened Bitcoin-Qt (Also tried this after downloading 0.8.1), not the same result, instead of a crash I get: 'wallet corrupt, salvage failed' message when launching, the wallet.dat file is replaced with a 'walletxxx.backup'
pywallet --dumpwallet which results in: ERROR:root:Couldn't open wallet.dat/main. Try quitting Bitcoin and running this again.
bitcointools: fixwallet (same error as pywallet)

Is this typical? What'd I do wrong? Should I not have run my wallet with 0.8.0-beta? Should I backup the file DAILY in-case of corruption? If the issue is just "InvalidChainFound" why would that affect my wallet?

At this point I'd be happy just to get my address/private-keys back.
