Partition Types

This is a quick reference list (some data may be misleading for your specific case).
Note: Sometimes there's only one way you can be sure of the exact purpose of an obscure or rarely used partition type: You must locate, examine and gather info about the utility that created the partition and/or ask the person who actually set up the disk what they're using that partition for!

(For a more detailed listing, see Andries Brouwer's Partition Type Indentifiers .)


NOTE: All Partition Type values listed below are in Hexadecimal.

Remember: Partition types do *not* necessarily specify a specific file system; e.g., 07h is used by both OS/2's HPFS and Windows NT/2000/XP/2003/Vista/2008/7/8's NTFS (all versions).

00 : -- Should NOT be used in an actual table entry! It does not indicate an unknown type, but rather an empty entry; in which case, all other fields in that 16-byte entry should be zero-filled as well.

Although there are 253 possible partition type values (05h and 0Fh having been acknowledged as special use cases), you'll almost never see any but a handful of these being used today. This is primairly due to the popularity of the IBM/Microsoft operating systems (FAT16, FAT32 and NTFS), and the many flavors of Unix (such as BSD) and all the Linux distributions, which have mainly settled on using type 83h for all their file systems; apart from swap partitions, which are type 82h.
