Thanks, but some clarification is needed. Now I have two drives, failed
and a spare. Both are 2TB in size. Failed drive probably has 1.6 TB
data I'd like to recover. It has only one partition I suppose. So, if
failed drive is for instance /dev/sdb and spare drive is for
isntance /dev/sdc, the right command will be ddrescue if=/dev/sdb
of=/dev/sdc/failed.img ? And also, you didn't answer this, what file
system the a spare drive ahs to be formated?
