Re: [Bug-ddrescue] gnu ddrescue and bad sectors

[Adrien Cordonnier]

Hi Vincenzo,

If you recover a disk image to a formatted partition, it is better to
recover to a ext4 partition. Several people including me have experienced
decreasing speed with a NTFS partition. It became so slow that the recovery
could not complete. The disk image will inherits the partitioning of the
corrupted hard disk. Testdisk can work directly with such disk image. If
you want to mount the partitions, you will need a tool such as kpartx.

If you recover to a new unformatted disk, make sure the disk is blank or
use ddrescue fill mode. If you don't, the former data on the new disk will
be kept where there are bad sectors.

Best regards,

Adrien
