The recover scan with pywallet on the 2TB drive found 4 possible wallets, 900 encrypted keys (newer wallets) and 1800 possible unencryptet keys. For some reason it only tried to recover the exact same 306 keys like the other scan, from the "recovered-wallet.dat" file, and it stopped at 20/306 this time too. Why didn't it try to recover the other keys? And why does it stop at 20?
