diskpart 'shrink' needs a little work...
I'm playing with BitLocker a little, and I need a small temporary partition to encrypt and decrypt on a frequent basis.
No problem, right? I can just open up Computer Management, select Storage, Disk Management, and then shrink a volume that has lots of space. [I can do the same with "diskpart" from the command line, if I choose to]
Oh, now, that's just perfect - I can't shrink my partition, and even if I do, I'll end up wiping out the existing partition?
Okay, so I realise that it's not likely to be quite that severe, but there's a little work needs to be put into the disk partition shrink mechanism in Windows Vista.
First, obviously, edge cases like the one above need to be handled properly.
Second, there needs to be an option that informs the administrator as specifically as possible what limited the shrink operation - which immovable file is sitting on the boundary of the maximum shrink area. That way, I can decide what the problem is - it's not the hibernation file (because I've deleted that), and it's not the pagefile (again, deleted); it's not even volume shadow copies, because I've disabled System Restore.
