Do you have any kinds of multi-controller, multi-disk, RAIDx, or other 
hardware or driver setup that could result in some drives being visible 
twice on your system?

To me it looks like you may have six controllers or interfaces on your 
system, two look like usual IDE/PATA/SATE, four something more complex.

Perhaps you could also show output from:

	$ $ df -a ; fsutil volume list
