Getting the error that you cannot import a foreign disk? Looked in the Event Viewer’s System Log to find: “A disk group with the specified name already exists”? Not to worry! There is a solution, it just isn’t obvious.
This requires some general comfort with regedt32.exe, and I have only done this under Windows XP Pro.
- Fire Up regedt32.exe.
- Navigate to : HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\dmio\Boot Info
- Right-mouse click on “Primary Disk Group” and select “delete” to remove it.
- Quit the registry editor.
- Reboot the machine.
Once the machine comes back up, you can go in to “Disk management” and successfully import the foreign disk.
