About “Foreign” Disk issue

You may encounter this issue if your PC has multiple operating systems installed: Windows XP Home Edition and another operating system (such as Windows 2000 Professional or Windows XP Professional) that uses dynamic disks that are not supported by Windows XP Home Edition, or on portable computers.

When moving a dynamic disk from one computer to another that does not support dynamic disk, the dynamic disk created on the previous computer will be marked as a foreign disk in Disk Management. This applies to Windows 2000, Windows XP 64-bit Edition, Windows XP Professional, or Windows Server 2003.

The main solutions to the Dynamic Foreign Disk issue

Using drive as ordinary disk?

You can add a dynamic disk to your computer's system configuration and thus be able to access the data on the disk.

To get started, import your external drive: right-click the drive and then click "Import External Drives". When you import a drive, any existing volumes on the foreign drive become available.

Right-click on the desired drive and click on "Import Foreign Drives". After that, the disk receives the status of "basic", it can be split and used like any regular disk.

Using a different OS or PC?

If you moved a disk group to another operating system or computer, it will be marked as "alien". You need to import this disk group at one time into the operating system. Otherwise, you will not be able to save the information.

In Disk Management, right-click one of the drives and select the Import External Drives option.

Next, all added disks and information about imported volumes will be listed, and you can understand whether all disks from the group will be imported. In this case, all partitions on these disks will have the Healthy status. If you see any other status, then not all disks from the group have been imported.

If drives are broken

Then open the DiskInternals RAID Recovery application and use the following instructions to restore the information you need.

  1. 1. Turn off the computer/server or NAS device and disconnect the drives that make up the RAID array.
  1. 2. Connect these drives to a running computer (after turning off its power).
  1. 3. Turn on a working computer, download and install RAID Recovery.
  1. 4. Launch the recovery wizard and follow its instructions carefully.
  1. 5. Select the desired RAID to restore and decide whether you prefer a full scan or a quick scan.
  1. 6. Any of the found files can be viewed for free.
  1. 7. To save found files from the array, you need to purchase a license; then complete this process and export the data from the restored array to the correct drive using the export wizard.
