A '''Basic Data Partition''' is a [[partition (computing)|partition]] on a [[data storage device]] that is used to hold discdisk volumes that are to be visible to [[Windows XP]] and later operating systems<ref name=GPTFAQ>{{cite web|url=http://www.microsoft.com./whdc/device/storage/GPT_FAQ.mspx|work=Windows and GPT FAQ|title=Windows GPT Implementation}}</ref>. The [[Globally Unique Identifier]] for the Basic Data Partition in the [[GUID Partition Table]] scheme is <tt>EBD0A0A2-B9E5-4433-87C0-68B6B72699C7</tt>.

According to Microsoft, the Basic Data Partition is the equivalent to partition types 0x06, 0x07, and 0x0B in the [[Master Boot Record|MBR Partition Table]] scheme<ref name=GPTFAQ />. However, in practice it is equivalent to partition types 0x01, 0x04, 0x0C, and 0x0E as well.

Line 20:

A Basic Data Partition can be formatted with any [[filesystem]] format, although most commonly BDPs are formatted with the [[File Allocation Table|FAT]] or [[NTFS]] filesystem formats. To determine which filesystem format a BDP contains, Microsoft specifies that one should inspect the [[BIOS Parameter Block]] that is contained in the BDPs [[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 (GUID <tt>AF9B60A0-1431-4F62-BC68-3311714A69AD</tt>). This is analogous to the conversion from partition types 0x01, 0x04, 0x06, 0x07, 0x0B, 0x0C, and 0x0E to partition type 0x42 on MBR partitioned discsdisks.
