PowerShell or Group Policy Objects in XP Pro SP2

[Tripredacus]

I need some help as searching for this is not very easy for me to find results. I need to limit a user from being able to delete a volume in Disk Management in Windows XP Pro SP2 with either Local Computer Policy or by use of PowerShell.

If you have no idea, is there a good place to find out how to make custom GPOs for the local system? Or any good PowerShell reference concerning limiting MMC options?

I already have Windows PowerShell Scripting Guide by Ed Wilson (2008) pn X14-15140, but it is a hard read to find this kind of specific info.

Thanks

Update: It looks like using i/x/CACLS would be the best, to deny all permissions to the volume which should stop users from deleting the partition. However, the volume has no drive letter. Is there a way to assign an ACL to a GUID or other system level descriptor for the volume?
