I wanted to try to put a hard drive & one DVD on one IDE channel, and the other HD & DVD on the other. But, of course, the cables won't reach.
Either way, I got another 80 wire cable for the secondary channel and made sure the jumpers were all set correctly and the drives were plugged in to the right plugs on the wire. Every seems to be working. BUT the new drive, for whatever reason, is not liking the HP cd-r discs I have here, for writing or reading. Hopefully that's it. It's not having a problem with the RI-DATA DVD's that I burned previously, or the spindle of Staples DVD+R's I have.
Thanks goes out from me to all those who replied.
