Partition Recovery

The first sector of NTFS partitions is reserved for the partition boot sector. This contains the information that allows the OS to read the partition. Without it, the partition cannot be accessed.

By its nature, NTFS keeps a backup copy of the boot sector on the last sector of the partition which can allow recovery programs to restore it. The FAT equivalent of this is also called the boot sector, and resides on the first sector of the partition. The difference is that FAT does not keep a backup copy of this information, making recovery much more difficult...

The first file stored on an NTFS partition is the Master File Table(MFT) which is essentially a listing of the names, properties and locations of all the other files in the partition. This is referenced by the operating system to access individual files.

NTFS stores a backup copy of this file. Data restoration software will attempt to access or restore a copy of the MFT in order to access files on the partition.
