delete unwanted EISA partition


I had to repair a mirror set on a Windows 2000 server, ML350, and unfortunately I made a reboot when the system told me to do so. So the new HDD got an EISA partition. I could not add this new HDD to the mirror set because of the existing part of the old mirror set has no EISA partition. So I searched for a solution and found a hint towards diskpart. I used this tool and achieved a completely clean disk again. So I was able to add this disk to the mirror set.
Fine. But now windows disk management shows me a missing offline disk, 8 MB, EISA. This is even for diskpart undeletable. When I try to delete it then I get:

DISKPART> select disk M0

Disk M0 is now the selected disk.


DiskPart was unable to clean the disk.
The data on this disk may be unrecoverable.

And here I show you what diskpart says when I enter DISKPART> list disk

Disk ### Status Size Free Dyn Gpt
-------- ---------- ------- ------- --- ---
Disk 0 Online 34 GB 8033 KB *
Disk 1 Online 34 GB 8033 KB *
Disk 2 Online 34 GB 0 B *
Disk 3 Online 34 GB 34 GB
Disk M0 Missing 0 B 0 B *

How do I get this DISK M0 away?
