Hey there pdeinc...
I'll pass on the only information that I have on this... (which may be completely off base)
It is my understanding that it is impossible to repartition a drive and keep any information intact.
If you do make an attempt at this (leagl discloser: Im not suggesting that you do) than make sure you have any information backed up on an external media source prior to attempting....
I hate it when companies set up hard drives like that...
Good on ya...
