Hi,
I think you dont need to make a fsck in the image, it is useless. You
want to rescue your important data from that image. First of all, did
you have partitions in that hd ? Or only / ? In case you had more
partitions, you need to make an image from each partition. Maybe only
for /home, if there were all the data you need to backup. You dont
need to backup the binaries or config files or /dev, etc (in case you
dont want to make a forensic analysis).
I havent used dd_rhelp, but maybe is similar to dd. For each of the
partitions you have to:
dd if=/*source* of=/*destination*
where:
if = infile, or evidence you are copying (a hard disk, tape, etc.)
source = source of evidence
of = outfile, or copy of evidence
destination = where you want to put the copy
Then you should be able to mount it. I see that you copied the image
in a "new" harddrive, does this hd have already a filesystem ? If yes,
you should mount it. First you must mount the harddrive and then mount
the image in a mountpoint.
# mount -o ro,loop,nodev,noexec,noatime /mnt/hdb1/hda1_rescue.img /mnt/hda1
