Microsoft basic data partition

In Microsoft operating systems, when using basic disk partitioned with GUID Partition Table (GPT) layout, a basic data partition (BDP) is any partition identified with Globally Unique Identifier (GUID) of EBD0A0A2-B9E5-4433-87C0-68B6B72699C7.
According to Microsoft, the basic data partition is the equivalent to partition types 0x06 (FAT16B), 0x07 (NTFS or exFAT), and 0x0B (FAT32) in the traditional MBR partition table. In practice, it is equivalent to 0x01 (FAT12), 0x04 (FAT16), 0x0C (FAT32 with logical block addressing), and 0x0E (FAT16 with logical block addressing) types as well.
A Basic Data Partition can be formatted with any filesystem format, although most commonly BDPs are formatted with the NTFS, exFAT, or FAT32 filesystem formats. To programatically determine which filesystem format a BDP contains, Microsoft specifies that one should inspect the BIOS Parameter Block that is contained in the BDP's Volume Boot Record.
When a Microsoft operating system converts a GPT-partitioned basic disk to a dynamic disk, all BDPs are combined and converted to a single Logical Disk Manager data partition identified with GUID AF9B60A0-1431-4F62-BC68-3311714A69AD. This is analogous to the conversion from partition types 0x01, 0x04, 0x06, 0x07, 0x0B, 0x0C, and 0x0E to partition type 0x42 on MBR partitioned disks.
Linux used the same partition type GUID for basic data partition as Windows prior to introduction of a Linux specific Data Partition GUID 0FC63DAF-8483-4772-8E79-3D69D8477DE4 (see GUID Partition Table).
