It is vital that you remember the exact cable and connector arrangement of your
hard disks, particularly if you are using a RAID (Redundant Array of
Independent Disks) configuration. If you fail to restore the arrangement so that
all cables and plugs are as they were originally, you risk losing all the data on
your hard disks.
