I can't get my computer to recognize my new Zip 8x4x32 CDRW drive.

It's a Dell XPS-D series system, which I did the Intel Celeron 533 upgrade
on--so it has Intel Bios A14.

It has a CD-ROM and a Zip 100 drive, both IDE, originally. The
configuration was like this:

Primary IDE Master: IBM Harddrive
Primary IDE Slave: NONE
Secondary IDE Master: Samsung CD-ROM
Secondary IDE Slave: Zip 100 Drive

Now, unfortunately, the manual stated that I shouldn't put the CDRW on the
same IDE channel as the hard drive. Originally, I had intended to move
the ZIP to IDE Channel 1 slave, or move the CD-ROM to channel 1 slave.
But when I saw the way the IDE cables were laid out inside the system
(both power and IDE cables) I realized that I couldn't physically move
either one to the IDE cable for channel 1--the HD's cables were just too
short.

So, I decided to disable the Zip and put the CDRW as the slave on Channel
2. I unplugged both power and IDE from the Zip and installed the CDRW.

I followed the installation to the letter. My CD-ROMs jumper was set to
cable select, which I didn't change, and my new CDRW was set at slave on
its jumper.

I powered up--now I had no CD-ROM and no CDRW either! I changed the
jumper on the CD-ROM to 'master', with no effect, and even changed both
to cable select, with no effect. I did that because I noticed that the
old Zip appeared to be on cable select also, so I thought maybe the BIOS
would work it out.

So I still have absolutely no CD drives at ALL! I checked all the cables
and they appear to be tight. What do I do, and ideally, how do I get my
Zip back and configured if I manage to work this problem out first?

Please help. Thanks in advance.

Update: I kinda have egg on my face. After swearing all the cables were
properly connected, I quadruple-checked and the mobo one was loose.

But despite the system re-recognizing the CD-ROM, the CDRW is still
missing according to the BIOS and Win98SE. The drive light blinks
constantly, though. I tried the master-CD-ROM and slave-CD-R/W jumper
settings, and then changed them both to cable-select, to no effect.

At least I am one step closer. Anyone have theories what to try next? I
may try making the CDRW master and CD-ROM slave, after checking
connections, but now I must turn in for the evening.

why not just get a longer ide cable for your Harddrive? then you can put:

Primary Master HDD
Primary Slave Cd-rom

Secondary Master Zip whatever whatever..

Thanks for the suggestion, but I thought of another one: could I get an IDE extension cable that is 'male' on one end and 'female' on another, and then connect the Zip drive to the primary IDE slave spot? Would this be possible and would it hurt the computer's performance?

Someone suggested that I try jumpering both drives to 'cable select.' It think I'll attempt that next and hopefully it will resolve, but at least I have my CD-ROM back.

I have never used cable select before. I am not even sure what it is. Why not try Master and Slave?

PROBLEM SOLVED! I is so happy! Yippie kay yo!

Serves me right for listening to Iomega's "expertise." I put the CDRW on Master, and the CD-ROM on Slave in the 2nd IDE channel, and now everything works like a charm.

The Iomega Zip, as per very good advice I have received, will get a few new cables and will become primary Slave.

I have read time and time again that you should NEVER put any CD drives on the HD's primary channel, because it'll slow your system to a crawl (well, maybe not if you're lucky & wealthy enough to be using SCSI).

You shouldn't really put CD-RWs on the same channel as a HD because IDE devices have trouble transferring data quickly between two devices on the same channel, which in the case of CD-RWs leads to the dreaded buffer under-runs...
