I think you would be best off with an 80-wire ribbon cable. They are 
dirt cheap.

What is the brand & model of the DVD reader (or is it a DVD burner) 
which you are installing?

What is the brand etc of the CDROM you are replacing?

Hold on here...we are getting into terminology hassles here....

"DVD is still CS (cable select) on its own cable as master": why do you 
say it's "master"? Because it is at the end of theribbon cable?

"HD is Master......": similar question- it is Master because the jumper 
is set to Master - and not CS - or it is CS and sitting at the end of 
the cable?

It would be a lot easier if BOTH devices were configured the same - put 
BOTH as MASTER, on their own indivudual cables, using the* jumpers*. 
This will eliminate a variable out the equation.

OK - a big question: is the CD or DVD you are putting into the drive a 
blank or does it have data/movie on it?


(Another big queston: what happens when you put back the CDROM with 
EXACTLY same settings as you now have on the DVD and HD? Trying to see 
if the DVD unit is a bummer and needs to be taken back to the store.)
