When you import dynamic disks that are listed as foreign in the Windows 2000 Disk Management tool, you receive the subject error? After you respond, the imported dynamic disks are displayed as foreign disks?
If the foreign disks use the same disk group name as the current computer, you will receive this error.
If your system/boot drive is still a basic disk, use Regedt32 to navigate to:
Delete the Primary Disk Group key and restart your computer. Try importing the foreign disk again.
If your system/boot drive is a dynamic disk, move the foreign disks to another Windows 2000-based computer that has a different disk group name to import them.
