Re: [Bug-ddrescue] Error in logfile line 0

[Gonzalo de la Mota]

Hola de nuevo,

Thanks for the information and quick reply. After trying to see if the file
was corrupted in any way I finally gave up.

Today I unplugged both disks, rebooted, and now it works.

Thanks again for the help and sorry for the false bug report.
