Dynamic disk shows as “Foreign”

What is Dynamic Foreign Disk?

When you move a dynamic disk from one computer to another that does not support dynamic disks, such as any version of Windows Home, the dynamic disk that was created on the previous computer is marked as Foreign in Disk Management. (Dynamic Disks are not supported by Windows XP Home Edition or by portable computers.) In addition, if your computer has a dual-boot configuration and one of the operating systems does not support dynamic disks, the disk will show as Foreign. One of the following might explain why a dynamic disk appears as a Foreign disk:

The dynamic disk comes from another computer that is running Windows 2000, Windows XP 64-Bit Edition (Itanium), Windows XP Professional, or a member of the Windows Server 2003 family. The computer is configured to boot to another operating system that does not support dynamic disks, such as Windows 2000 Professional or Windows XP Professional, on a computer running Windows XP Home Edition or a portable computer.

How to import data from an external hard drive without losing any information

When a dynamic disk becomes "foreign," the data on it is still present but invisible. Follow the instructions in either of the following two methods to move and import the foreign disk.

1. How to Connect an External Hard Drive in Two Ways

"Import external disk in Disk Management"

To access data on the disk, you need to add it to your computer's system configuration. In Disk Management, right-click on the "Foreign Disk" and select "Import Foreign Disk." After this, all volumes present on the foreign disk will become visible and accessible.

Use DiskPart to import an external disk

Type CMD in the search box, right-click Command Prompt, and select "Run as administrator." Type diskpart and press Enter. Type list disk and press Enter. Type select disk n and press Enter (where "n" is the number of the disk you want to move). Type import [noerr] and press Enter.

Will importing from an external hard drive damage the data?

Adding the disk to “System Configuration” on a dynamic disk supported system should not in any way harm your data. This should be completely harmless, and your data should remain intact. However, if you have Windows XP Home Edition, you will not be able to use the disk again by “importing” it. Your only option is to delete all the data on the disk and then convert it back to a basic disk, which will cause you to lose your data. To do this:

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