What is Foreign Dynamic Disk and Why is Dynamic Disk Showing Foreign

When you move a dynamic disk from one computer to another one 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 Manager. 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.

Two Ways to Access and Fix Foreign Dynamic Disk Easily

In fact, if your dynamic disk is showing foreign, the data on the disk is still there. The data is just invisible. To fix this, you must follow the two ways below.

1. Import the foreign disk

To access data on the disk, you must add the disk to your computer's system configuration. In Disk Management, right-click the foreign disk and select "Import Foreign Disks". After that, any existing volumes on the foreign disk become visible and accessible. 

2. Convert Foreign Dynamic Disk to Basic Disk

As we know, some versions of Windows cannot access the dynamic disk, so you need to convert the foreign dynamic disk to basic by right click the foreign disk and select "Convert to Basic Disk". This operation will wipe out all the data on the disk. If you want to convert dynamic disk to basic without data loss, please read on.
