Microsoft-defined GPT attribute flags for BDPs[1]
Bit number Meaning
60 The volume is read-only and may not be mounted read-write.
62 The volume is hidden.
63 The operating system may not automatically assign a drive letter to the volume.

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 <templatestyles src="Mono/styles.css" />EBD0A0A2-B9E5-4433-87C0-68B6B72699C7.[2]

According to Microsoft, the basic data partition is the equivalent to master boot record (MBR) partition types <templatestyles src="Mono/styles.css" />0x06 (FAT16B), <templatestyles src="Mono/styles.css" />0x07 (NTFS or exFAT), and <templatestyles src="Mono/styles.css" />0x0B (FAT32).[2] In practice, it is equivalent to <templatestyles src="Mono/styles.css" />0x01 (FAT12), <templatestyles src="Mono/styles.css" />0x04 (FAT16), <templatestyles src="Mono/styles.css" />0x0C (FAT32 with logical block addressing), and <templatestyles src="Mono/styles.css" />0x0E (FAT16 with logical block addressing) types as well.

A basic data partition can be formatted with any file system, although most commonly BDPs are formatted with the NTFS, exFAT, or FAT32 file systems. To programmatically determine which file system 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 <templatestyles src="Mono/styles.css" />AF9B60A0-1431-4F62-BC68-3311714A69AD. This is analogous to the conversion from partition types <templatestyles src="Mono/styles.css" />0x01, <templatestyles src="Mono/styles.css" />0x04, <templatestyles src="Mono/styles.css" />0x06, <templatestyles src="Mono/styles.css" />0x07, <templatestyles src="Mono/styles.css" />0x0B, <templatestyles src="Mono/styles.css" />0x0C, and <templatestyles src="Mono/styles.css" />0x0E to partition type <templatestyles src="Mono/styles.css" />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 <templatestyles src="Mono/styles.css" />0FC63DAF-8483-4772-8E79-3D69D8477DE4.[3]
