Highly suggest you backup what is on d: and with Disk Administrator delete
the d: from within NT. Then run PM and expand into the available space.
BE WARNED!!! Do not exceed 7.8gig or you can render your NT system
nonbooting. This is due to a ntfs/bios boot bug.
Your least risky course of action would be to move files and folders to d:
and simple reestablish sharepoints.
