I managed to get my hands on a Clariion CX600 whihc I have running in
my basement right now. The only thing wrong is that I have one bad
drive. I found a replacement for $100 but it looks like it has the
wrong firmware on it which is preventing the Clariion from recognizing
it. The firmware version on the rest of the drives is 7A04 (CLAR146).

Does anyone know where I can find that version of firmware or any
version which would work in a CX600?

Thanks, Mark.
