disktype 9

disktypes purpose of disktype is to detect the content format of a disk or disk image. It knows about common file systems, partition tables, and boot codes.
The program is written in C and is designed to compile on any modern Unix flavour1. It is self-contained and in general works without special libraries or headers. Some system-dependent features can be used to gather additional information.
As of version 8, disktype knows about the following formats:

- FAT12/FAT16/FAT32
- NTFS
- HPFS

Other structures:
- Debian split floppy header
