Hold the phone.... The Maxtor on the secondary controller (SCSI) is being
recognized as C: ??? Shouldn't the IDE controller's first drive be required
to have a C: partition? It sounds like to me preliminarily that the 
IDE controller is not setup correctly...

I have noticed on a couple of my drives that this happens also. I think
some manufactures preformat their drives and figure that you won't need
to re-format them. I have a drive that works fine and returns immediately
from a format with no errors...

Well, speaking from experience, if you try to use a primary "AT" style 
controller with an Adaptec secondary controller with ISC 2.0.2, it won't
work. I had the exact same problem before I upgraded to ISCv 2.2.

Good luck, Mike..
