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.
In the GPT scheme, BDPs are the only partition types which Windows XP 64-bit can mount and normally assign drive letters.
According to Microsoft, the basic data partition is the equivalent to partition types 0x06, 0x07, and 0x0B (FAT16, NTFS, FAT32) in the traditional MBR partition table. In practice it is equivalent to 0x01, 0x04, 0x0C, and 0x0E (various older FAT partitions) types as well.
A Basic Data Partition can be formatted with any filesystem format, although most commonly BDPs are formatted with the FAT32 or NTFS 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 typically uses the same partition type GUID for basic data partition as Windows. However, a Linux specific Data Partition GUID 0FC63DAF-8483-4772-8E79-3D69D8477DE4 has been proposed. See GUID Partition Table.
Famous quotes containing the words basic and/or data:
“When you realize how hard it is to know the truth about yourself, you understand that even the most exhaustive and well-meaning autobiography, determined to tell the truth, represents, at best, a guess. There have been times in my life when I felt incredibly happy. Life was full. I seemed productive. Then I thought,”Am I really happy or am I merely masking a deep depression with frantic activity?” If I don’t know such basic things about myself, who does?”
—Phyllis Rose (b. 1942)
“To write it, it took three months; to conceive it three minutes; to collect the data in it—all my life.”
—F. Scott Fitzgerald (1896–1940)
