There are jumpers on the CDROMs that let you set up the drives as master 
and slave. Since the drives seem to be working and are recognized as hdc 
and hdd, I doubt that is the problem.
The only things that I can think of are for the cables being defective 
or loose. Another possibility is that having both CDROMs on the same 
controller stresses the IDE controller on your system board. I had an 
old Memorex that loaded down the controller  heavily, making both 
devices fail.
Check the jumpers on the drives and set one to master, check cables. Try 
one connected at a time and see if the errors are specific to either device.

Just a few things that I'd try.
