Have you tried Get Data Back for NTFS? (assuming that's your filesystem)

Already tried pywallet on the old backup. The address doesn't show.
Yes, i have installed a new OS. Used a recovery tool but the wallet.dat is corrupt.

Try pywallet on the formated HDD. It seems to me that you used pywallet on one of your older backups and a file recovery tool for the wallet.dat on the formated HDD. I want you to use pywallet to scan your formated HDD to find ALL *coin private keys, encrypted and decrypted.
Like I said, turn off that HDD and only connect it as a secondary disk.
If you need further instructions, please tell us which OS you're using, at least. And please, let it not be windows lol

PS: se quiseres ajuda em PT podemos falar pelo gtalk ou assim, mas desliga-me esse disco rígido, por favor Smiley

É windows 7. Sad
Mandei PM.

EDIT1: A usar o pywallet no disco como disseste.

EDIT2: Found 8 possible wallets
           Found 2841 possible encrypted keys
           Found 452 possible unencrypted keys

EDIT3: Found address but not the one i need. Sad

EDIT4: Fiz scan as partiçoes todas. Encontrou varios edereços mas nenhum é o k eu procuro. Sad

Bitcoin QT wallets aren't deterministic. That is, you can not recover coins from addresses generated after the backup was made. You have to make a new backup when you generate new addresses. Encryption or lack of it doesn't matter.

Does that answer your question?

So the backup of the wallet before encryption is no good for recovering the lost address?
Yes, *if* the lost address was not generated before you made the backup. You'd be best off with psy, trying to recover the most-recently-modified wallet if possible. ETA: Missed second line in your response to psy. Sorry for your loss.

On many non-QT clients, wallets are deterministic (addresses it generates are predetermined), where one seed can provide all future addresses which will be generated. You only need to make one backup. With QT, you need to regularly back up your wallet whenever you generate new addresses because it generates addresses randomly.

Did you rewrite the formated drive with a new OS? You may wish to try pywallet to see if you can recover the private keys from disk, in case they weren't rewriten yet. Pywallet can recover encrypted private keys, but you'll need to give it a list with the passphrase(s) for the wallet(s)

1st thing: turn off that hard drive in case you're using it. Connect it only as a secondary hard-drive, don't run your OS from it, to avoid further damage.

Hi

I have a problem.

I have a issue whit my computer and i had to format the drive.
The wallet that was on the drive was encrypted, but the backup that i have isn't.
I received some coins on the encrypted wallet that don´t show on the backup.
Are those coins lost?
