How to dump private keys from corupted un-encrypted wallet.dat with btc on it ?

[comrzzz]

I received bitcoins to one adress on my wallet, but Bitcoin-QT didn't synchronized till the end beause I didn't had enough space on hard drive. I backed up wallet and whole /.bitcoin folder.
Newly synchonized Bitcoin-Qt could not open that wallet and it says it's corrupted. Blockchain couldn't open it and pywallet couldn't dump keys.

How can I recover it ? If I am using pywallet to recover it, what exactly should I type ( I have Ubuntu ) and how can I choose that pywallet doesn't try to recover wallet from whole partition but from chosen file ?

If I open wallet.dat with hex editor can I find there private keys and how to recognize them ?
Are there some other ways to dump keys ?

Thx

Try starting Bitcoin Core with the -salvagewallet option and then dumping the private keys if that works.

You should start Bitcoin Core with the -prune=550 option so that it does not take up as much disk space. This will delete old blockchain data and reduce the storage space required.

good luck op, you're not alone in needing help here.

Depending on the type or corruption I might be able to recover your key. Please PM me your wallet.dat and I will see what I can do.

Moritz30 - can you help me?

I have the same issue, a corrupt file that was overwritten....
I have a corrupt wallet.dat file.

If you can help get my key, I will pay you.

Be careful just passing anyone you wallet.dat, that gives them your bitcoin. I'd suggest sticking to self help walkthroughs you can do yourself before resorting to possibly losing your coins. 

Not to say the offers to help aren't genuine, they very well may be. However caution is warranted.

I have received his wallet.dat and can say it is corrupted in a not-slightly way so just using normal methods will probably fail
