Hi Brian,
I generally think that your approach is fine, especially because you
mention bad sectors. With dd you get everything from the failing disk
and you can worry about recovering files later. I would however suggest
the following modification:
make partition on /dev/hdb; mount it
dd if=/dev/hda1 of=/mnt/hdb1/backup_dd_hda1.img
dd if=/dev/hda2 of=/mnt/hdb1/backup_dd_hda2.img
dd if=/dev/hda3 of=/mnt/hdb1/backup_dd_hda3.img
You can then mount your partition images with
mount -o loop /mnt/hdb1/backup_dd_hda1.img /mnt/loop1
mount -o loop /mnt/hdb1/backup_dd_hda2.img /mnt/loop2
mount -o loop /mnt/hdb1/backup_dd_hda3.img /mnt/loop3
and work on them/fix them/copy them as you like.
