Fault-Tolerant Disk Management

Ftdisk was used in Windows NT to manage partitions and all fault-tolerant volumes. In Windows 2000, FTDisk is used to manage basic partitions and fault-tolerant volumes from Windows NT 4.0.

Ftdisk manages basic disks. Basic disks can be partitioned with and recognized by Microsoft® MS-DOS®, Windows 95, Windows 98, and Windows NT. A basic partition does not provide fault tolerance or multiple disk volume functionality. Basic partition configuration is recorded in a few kilobytes of data at the beginning of the disk. Existing fault-tolerant volumes (Ftdisk sets) configured on Windows NT 4.0 can still be used on computers running Windows 2000 or converted to dynamic volumes.
