ok guys, rescan didn't work, yet it gave me an idea... I pulled the old bitcoin-qt version including wallet and chain files from 2 weeks ago using time machine...

balance looks ok and it's not infected with unknown transactions... since there are many transactions on that wallet and i think it is dating from early 2011, I will just forward funds to another one which is using latest bitcoin-qt and download the whole chain again... also, i had a hard drive accident in june 2011 and i changed the whole computer couple of months ago... it could be that just the crc during copying on backup caused the craziness on my piece of blockchain since it has changed a couple of hard drives in the last 2 years...

many thanks for assistance...

cheers



Well, you could spend money on bitcoin, and if you restored a backup from 2 weeks ago, and if bitcoin-qt hadn't yet caught up with the blockchain, it would still show your spent balance.  But you couldn't get any confirmations if you tried to spend them.  So this is not really a definitive restoration until the old client has caught up with the blockchain.  So make sure the client is caught up with the blockchain before you try to spend them (make sure it no longer says "unsynchronized").

Good luck.

If you still can't figure it out, you could try sending your wallet.dat file to a very trusted member here. Someone who has good reputation. They will see what they can from your file. Then they can send you back all (or almost all) of your bitcoins to your new wallet.

But try doing everything by yourself first.

Wallet is in sync now. Guess that's a good sign. Will try to do a test transaction.

Great, I'm glad.  For the reference of future readers, the fact that you were able to retrieve them using Mac TimeMachine means that if this approach hadn't worked, someone would likely have been able to guide you to get your Bitcoins through using something like pywallet to dump the keys.  So if you "loose" Bitcoins during an upgrade, they're almost certainly still there, and if you remain calm like marra you should be able to retrieve them.

In any case, glad you got your coins back marra.   Well done.

In the future, all of this will be easier...  Getting better by the day.

And the transfer is complete, 6 confirmations... Smiley woohooo, blockchain kept its integrity and I saved my BTC funds...

I propose to everyone to backup these 3 things before upgrading bitcoin-qt:

- wallet.dat
- a whole copy of last working blockchain
- previous working version of bitcoin-qt

Thanks for all the ideas guys, this makes me even more confident in the future of btc...
