Before Symantec took over Power Quest I would have suggested Partition
Magic. But since they now own the company & thus Partition Magic I'm
not sure it is safe to use. I haven't trusted Symantec for so long all
I can remember of trusting them was before I ever used Windows 3.x &
that was back when Peter Norton was more then a figure head.
To my knowledge you can only have one extended partition on any physical
drive, but then again I could be wrong, in which case I'd like to know
