If you have UTF8 set as your default character encoding, you should hopefully be OK. If it shows ? in the name and 0 bytes size, it is likely a corrupt file. You can also try ddrescue with --input-position=<bytes> and --max-size=<bytes> to retrieve just the borked part of the disk. -- Regards, Mick
