What Is Dynamic Foreign Disk

When you move a dynamic disk from one computer to another, which does not support dynamic disk, such as all Windows home editions, and then the dynamic disk created on the previous computer will be flagged as a foreign disk in Disk Management. (Dynamic disks are not supported on Windows XP Home Edition or portable computers). Besides, if your computer is dual-boot and one of the operating systems does not support dynamic disk, the status of the disk will also be shown as a foreign disk. The following two points may explain why the dynamic disk is showing foreign:

• The dynamic disk comes from another computer installing Windows 2000, Windows XP 64-bit Edition (Itanium), Windows XP Professional, or Windows Server 2003 family Operating System.
• Computers are configured to dual-boot with Windows XP Home Edition and another Operating system (such as Windows 2000 Professional or Windows XP Professional) that uses dynamic disks, which are not supported on Windows XP Home Edition or on portable computers.

Does import a foreign disk destroy data?

Adding the disk to your 'system configuration' that supports dynamic disk won't destroy data in any way. It should be completely harmless to do, and your data should remain entirely intact.  But if you are on Windows XP Home, you cannot use the disk again through "Import Foreign Disks". The only way for you to do it is to erase all of the data from the disk and convert it to a basic disk. But then you'll lose data. The specific steps are as follows.

• Right-click each volume on the dynamic disk you want to convert to a basic disk, and then click "Delete Volume" for each volume on the disk.
• When all volumes on the disk have been deleted, right-click the disk, and then click "Convert to Basic Disk...".
