When you upgrade from basic to dynamic disk, you can create mirrors, stripe sets, extended volumes, spanned volumes, and RAID-5 volumes.

The dynamic disk volume information is stored in a private database at the end of the disk. Disks are numbered during the upgrade from basic to dynamic, which can cause them to be numbered quite differently from the numbering that appears in Disk Management.

Example

Disk Management may display:
Disk 0
Disk 1
Disk 2
Disk 3
If you first upgrade disk 2 to dynamic and then upgrade disk 3, the dynamic disk database would contain:
Harddisk2 Disk1
Harddisk3 Disk2
You can use the DmDiag Query command to display:
Disk group: Dg0

NOTE: The lines that start with dm diskn denote the dynamic disk private numbers that match the Disk Management snap-in.
