In the event of catastrophic platter damage heads are mapped to zones of the drive then sectors containing file system information and file entries are read to determine the location and amount of data.
Damaged areas of the media are avoided to retrieve data without further degrading the media.
Finally, remaining recoverable sectors around damaged areas of the media are recovered. File integrity is then verified by collecting reports of files containing unreadable sectors and files are repaired if possible.
Once a clean copy has been transferred to media, the steps vary depending upon what types of files are damaged.
