I've got a basic software mirror. One of the disks failed, so i replaced the hard disk drive. I installed the new disk. Now when i try and remove the old mirror (the disk is partitioned C, and D), i can remove the C drive mirror, but when i try and remove the D drive mirror, i get an error "logical disk manager: the requested object is in active use, operation not allowed", i've re-booted the server, in case something is running, but still get the same error?
Any ideas? I've checked out MS KB, and i can use a different application to manage this called diskpart, but i want to leave this as a last resort.
