Before starting checklist1. Check that you have a known-good hard disk with
enough free space on it.
WARNING: Never recover data to
the damaged drive. Doing so will cause further filesystem damage. It
is possible to recover data to a known-working partition on the same physical
disk, but it does require special consideration.
2. Make sure that you understand volume locations. That
means you should have clear understanding of the following question: "where is
the damaged volume located? what size it was?".
3. You need administrative access to the computer in order to be able to access the disk(s)
directly.
4. If physical damage is suspected, review the following
settings:
- Disks and partitions - review bad sectors handling and timeouts.
Adjust if required.
- Validation options - you may want to disable validation because
it generates additional disk load, which may be undesirable with a
damaged disk.
- S.M.A.R.T. options - review S.M.A.R.T. monitoring settings.
Adjust if required.
5. Make sure there is no "hibernation" involved if you
are moving
undamaged disks around several machines. Ensure the machine is properly shut
down before unplugging the good drive from it. This does not apply to the
damaged drive. If the drive failed with a system in a hibernated state,
attempting to complete a shutdown on it may actually make the things worse,
so you should just take the drive as it is.
