I'd recommend doing the same using ddrescue and would suggest always using
ddrescue as it provides you with status information (progress, errors,
...) and doesn't bail out if you get input/output errors.
And if you ever have filesystem errors (if the system wants to use fsck),
first check if you harddisk is not broken. As you don't want to run fsck
on a broken disk and risk loosing all your data. In that case, first
ddrescue everything to a new disk, and then perform an fsck.
