Windows 2003 basic disk won't convert.

HI All

I have an old HP DL 140 G2, that doesn't do hardware RAID so I am setting up software raid.

I have 2 x 74GB disk, Disk 0 has windows OS installed (Basic disk)
Disk 1 is blank.

When I try and convert the disk to dynamic through disk management after I select the disk and click next the tab just disappears.

When I use diskpart I get the following.

DISKPART> list disk

  Disk ###  Status      Size     Free     Dyn  Gpt
  --------  ----------  -------  -------  ---  ---
  Disk 0    Online        75 GB      0 B
  Disk 1    Online        75 GB    74 GB        *

DISKPART> select disk 0

Disk 0 is now the selected disk.

DISKPART> convert dynamic

The disk management services could not complete the operation.

Any ideas ?

Thanks Arm

I can convert Disk 1 to Dynamic and back to Basic with no issues.
Some of the RAID controllers steal a little bit from the beginning of the drive for metadata. Did you reformat the HD and use it as a non-RAID disk in this system w/o the RAID controller first to make sure all is well with the drive?

HI there

Yes the system has no raid controller so windows was just installed on drive 0 as an independent drive.

The weird thing is I have 4 servers the same, all created form the same storage craft image, and it works on 1 of the 4 boxes.

Very odd. Thanks

So ever run diagnostics on this disk?

Yes no reported problems.
Then do you meet the requirements for converting a disk to dynamic? I have seen this before. Specifically the constraint on the MBR free space.  See below
