SUMMARY
The FDISK program from MS-DOS 6.22 can remove Windows NT file system (NTFS) partitions on hard disk drives. However it, identifies these partitions as HPFS.



MORE INFORMATION
This misidentification is due to the method in which file systems are reported to the system. The System Identifier Byte in the partition table for both NTFS and HPFS is 0x07. This indicates an Installable File System (IFS) type. Both HPFS and NTFS are installable file systems.

Additional query words: FDISK NTFS HPFS
