Can data be recovered from a re-formatted RAID 1 volume?
Many times information is still recoverable, depending on how the drives were re-formatted. A high-level re-format (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. A low-level format routine (as performed using the controller software) will overwrite every sector, and in the process destroys the original data.
