Can this be causing the problem with the 300 GB drive on the other
controller?  What I don't understand is why is there a problem only
with one drive on the secondary controller?

As for the cdrom, how else can it be connected?  It will ALWAYS be
slower than the hard disk.  Or do you mean it should just not be
connected to the boot drive?  I never had such a problem before.  I'll
move around my drives and see what happens.

Thanks for your help.
