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.

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

Basic Data partitions are the only partition types (in the GPT scheme) to which Windows XP will normally assign drive letters.<ref>{{cite web|url=http://technet2.microsoft.com/WindowsServer/en/Library/ca099518-dde5-4eac-a1f1-38eff6e3e5091033.mspx|work=Microsoft TechNet|title=DiskPart documentation}}</ref>

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 BDPsBDP's [[Volume Boot Record]].

When a Microsoft operating system converts a (GPT -partitioned) "Basic[[basic Disk"disk]] to a "Dynamic[[dynamic Disk"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 disks.
