added exFAT to the commonly used "basic disk" (e,g,, GPT primary partition) fileystems
Line 15:
In the GPT scheme, BDPs are the only partition types which [[Windows XP]] 64-bit can mount and 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>
 
According to Microsoft, the basic data partition is the equivalent to partition types <tt>[[partition type#PID_06h|0x06]]</tt>, <tt>[[partition type#PID_07h|0x07]]</tt>, and <tt>[[partition type#PID_0Bh|0x0B]]</tt> ([[FAT16]], [[NTFS]] or [[exFAT]], [[FAT32]]) in the traditional [[Master Boot Record|MBR partition table]].<ref name=GPTFAQ /> In practice it is equivalent to <tt>[[partition type#PID_01h|0x01]]</tt>, <tt>[[partition type#PID_04h|0x04]]</tt>, <tt>[[partition type#PID_0Ch|0x0C]]</tt>, and <tt>[[partition type#PID_0Eh|0x0E]]</tt> (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 NTFS, FAT32exFAT, or NTFSFAT32 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 <tt>AF9B60A0-1431-4F62-BC68-3311714A69AD</tt>. This is analogous to the conversion from partition types <tt>0x01</tt>, <tt>0x04</tt>, <tt>0x06</tt>, <tt>0x07</tt>, <tt>0x0B</tt>, <tt>0x0C</tt>, and <tt>0x0E</tt> to partition type <tt>[[partition type#PID_42h|0x42]]</tt> on MBR partitioned disks.
