So I'm looking at the command pywallet.py --recover and it looks like it requires a size option be set. How do you what number to put in there? The rest of the command, seems easy enough.
The size option is there mostly for hard drive scans. For a wallet, just choose a size that's larger than the wallet size.
You need to append a (strange) unit to the end of the size, so for example --recov_size=100Mo means 100 megaoctets.
(Be sure to take a backup of the wallet file before running pywallet on it, just in case)
