If a dynamic disk, such as one with a globally unique identifier (GUID) partition table, contains volumes that use other disks (spanned, stripped, mirrored, or RAID-5 volumes), the other disks in the group (non-GUID partition table disks that were brought along with the GUID partition table disk) may be reconfigured if you move the drives between computers.
This behavior can occur because the Logical Disk Manager service supports only one dynamic disk group ID on each computer. When the disks are moved back to the original computer, two new dynamic disks appear on the computer. The disk set ID of one of these disks (the GUID partition table disk) matches the disk set ID in the registry because the GUID partition table dynamic disk was created on the computer originally. The other disk has a different disk set ID because the configuration was modified by the other computer. The computer trusts the GUID partition table disk, and sets the properties of the incoming disk set according to the database that is stored on this disk. This means that the original GUID partition table configuration is restored and the modified configuration of the second disk (and also the data) is lost.
