In short,
- I bought a few BTC years ago when they were very cheap.
- I reformatted my HDD and reinstalled the OS.
- I have used PhotoRec and http://www.cyplo.net/2012/04/01/bitcoin-wallet-recovery-photorec/ to recover 3 .dat files. Searching only for the ''detection signature'' of a Bitcoin wallet.dat
And the confusing part (if reformatting a hard drive containing bitcoins was not confusing enough!) is that the recovered .dat files are 7GB , 13GB and 8 kb.
Obviously, trying to use the recovered wallet.dat with Bitcoin-qt failed.
Chances are that these .dat are not wallets but I though this would be worth a shot considering how massively more valuable BTC are compared to 3 years ago.
Anything I can do with these recovered files?
Thank you!
