Algorithms identifying the file system in a partition type 07 must perform additional checks.

The partition type is identified by a 1-byte code found in its partition table entry.

Note that the partition types should be changed to 0xFD with fdisk to indicate that they are mirrored devices.

Supported (guessable) filesystem or partition types:

Linux never had a separate unique partition type GUID defined for its data partitions.

The partition type of an extended partition is ( addressing) or (LBA addressing).

It does so by "asking" filesystem recognition modules if they think a given sequence of sectors resembles the beginning of a filesystem or partition type.

The first 16 bytes designate the partition type globally unique identifier (GUID).

Linux typically uses the same partition type GUID for basic data partition as Windows.

So the table specifies which operating systems or disk-related products originally introduced an ID and what file system or special partition type they mapped it to.

As such it is usually used only for the final steps of the motion estimation process, such as deciding between different partition types in H.264/AVC.

If there is more than one extended partition in a partition table, only the logical drives in the first recognized extended partition type are processed.

EISA partition, An OEM disk partition type.

A single partition type of , encompassing the entire GPT drive, is indicated and identifies it as GPT.

This is a list of known Master Boot Record partition types on IBM PC compatible computers:

In the GPT scheme, BDPs are the only partition types which Windows XP 64-bit can mount and normally assign drive letters.

The appropriate file system driver for the partition type (NTFS, FAT, or FAT32) which the Windows installation resides are amongst them.

As is the nature and purpose of GUIDs, no central registry is needed to ensure the uniqueness of the GUID partition type designators.

TechNet article: the lower 4 bytes representing partition type independent attributes, and the upper 4 bytes are partition type dependent.

Acronis Secure Zone is a hard disk partition type created and used by Acronis True Image (ATI) as a backup storage target.

This is analogous to the conversion from partition types , , , , , , and to partition type on MBR partitioned disks.

The File Allocation Table file systems have made use of quite a number of partition type codes over time due to the limits of various DOS and Windows OS versions.

Other extended partition types which may hold EBRs include the deliberately hidden types , , and , the access-restricted types and , and the secured types and .

Though a Linux operating system may recognize a number of different file systems (ext4, ext3, ext2, ReiserFS, etc.), they have all consistently used the same partition type code: (Linux native file system).

While not officially maintained, new assignments should be coordinated, in particular any new temporary partition type assignments for local or experimental projects can utilize type in order to avoid conflicts with already assigned types.
