Microsoft basic data partition
open-in-new
Microsoft-defined GPT attribute flags for BDPs<a class="footnote-ref" id="fnref:1" href="#fn:1"><sup>1</sup></a><table><tbody><tr><th>Bit number</th><th>Meaning</th></tr><tr><td>60</td><td>The volume is read-only and may not be mounted read-write.</td></tr><tr><td>62</td><td>The volume is hidden.</td></tr><tr><td>63</td><td>The operating system may not automatically assign a drive letter to the volume.</td></tr></tbody></table> <p>In <a href="/facts/Microsoft/nGIDDXdx">Microsoft</a> <a href="/facts/Operating_system/8XTuvMh2">operating systems</a>, when using <a href="/facts/Logical_Disk_Manager/etoULoUj">basic disk</a> partitioned with <a href="/facts/GUID_Partition_Table/Tbj7cPSs">GUID Partition Table</a> (GPT) layout, a basic data partition (BDP) is any <a href="/facts/Partition_(computing)/wrBk5RRS">partition</a> identified with <a href="/facts/Globally_Unique_Identifier/SUtkYJPe">Globally Unique Identifier</a> (GUID) of EBD0A0A2-B9E5-4433-87C0-68B6B72699C7. </p><p>According to Microsoft, the basic data partition is the equivalent to <a href="/facts/Master_boot_record/nEJerupp">master boot record</a> (MBR) partition types <a href="/facts/Partition_type/su2cLH6o">0x06</a> (<a href="/facts/FAT16B/uFvpmWxa">FAT16B</a>), <a href="/facts/Partition_type/su2cLH6o">0x07</a> (<a href="/facts/NTFS/dryNM3BK">NTFS</a> or <a href="/facts/ExFAT/w9R3QhPC">exFAT</a>), and <a href="/facts/Partition_type/su2cLH6o">0x0B</a> (<a href="/facts/FAT32/uFvpmWxa">FAT32</a>). In practice, it is equivalent to <a href="/facts/Partition_type/su2cLH6o">0x01</a> (<a href="/facts/FAT12/uFvpmWxa">FAT12</a>), <a href="/facts/Partition_type/su2cLH6o">0x04</a> (<a href="/facts/FAT16/uFvpmWxa">FAT16</a>), <a href="/facts/Partition_type/su2cLH6o">0x0C</a> (FAT32 with <a href="/facts/Logical_block_addressing/WWtvA0E2">logical block addressing</a>), and <a href="/facts/Partition_type/su2cLH6o">0x0E</a> (FAT16 with logical block addressing) types as well. </p><p>A basic data partition can be formatted with any <a href="/facts/File_system/FdPm90uc">file system</a>, 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 <a href="/facts/BIOS_Parameter_Block/pRQGRRsC">BIOS Parameter Block</a> that is contained in the BDP's <a href="/facts/Volume_Boot_Record/yLef5Tvg">Volume Boot Record</a>. </p><p>When a Microsoft operating system converts a GPT-partitioned basic disk to a <a href="/facts/Dynamic_disk/etoULoUj">dynamic disk</a>, all BDPs are combined and converted to a single <a href="/facts/Logical_Disk_Manager/etoULoUj">Logical Disk Manager</a> 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 <a href="/facts/Partition_type/su2cLH6o">0x42</a> on MBR partitioned disks. </p><p>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. </p>
