Can data be recovered from a re-formatted RAID 5 volume?
Many times information is still recoverable, depending on how the drives were re-formatted. Re-formatting a volume using Windows, for example, will create what will appear to be a new “clean” volume – but the original data will still be on the disk in the “free and available” space. However, a low-level format (usually performed through an on-board RAID controller utility) will “wipe” or overwrite every single block on a drive. Unlike an O/S (or “high-level”) format, a low-level format normally is slower, takes a considerable amount of time and destroys the original data.
