ATAPI ZIP drive makes CD ROM unavailable

When I connect a 100MB internal ATAPI zip drive to the same cable as my CD
ROM drive, the CD ROM drive disappears. The zip drive works fine, but I
don't have a drive letter for the CD ROM drive.

Here's what I tried so far:
1. I ensured that the CD ROM was slave and the zip drive master (CD missing)
2. I assigned the zip drive the letter E instead of D (no help)
3. I tried making the zip drive slave and the CD ROM master (CD missing)
4. I tried placing the zip drive on the same IDE cable as the hard drive
but set as slave (the performance was unbearable).

System details: IBM Thinkcentre A30 (P4/2.8GHz), XP Pro SP2, both cables
are high speed ATA100/133 EIDE cables.

Any assistance is greatly appreciated!

Assigning the ZIP® drive a letter higher than N might do the trick though
this usually only works with USB drives. I'd say Z (for zip of course) and
see if that does the trick. You may also then need to assign the drive
letter of the CDROM back to where it was before.

Well, I have network drives from F: on, so I can't go higher than G. In any
event, this didn't solve the problem. Also, the CD ROM drive was D:
previously and so the Zip drive at E: should not interfere with this
assignment. Further, since the CD ROM drive isn't listed in device manager
nor in Disk Management, there is no way for me to set the CD ROM drive
letter. Of course, disconnecting the Zip drive from the EIDE cable causes
the CD ROM drive to appear as drive D every time. Any other ideas?

Not really, as I mentioned from the first post that's usually the USB fix.
From F on (all the way to Z???) is taken??? This could be problematic... The
trouble you mentioned seems to occur mostly in removable media (it's cropped
up with USB ZIP® drives in the past) but more often is seen with people
complaining about flash ROM such as the cards from various cameras or in
card readers. The symptoms are the same though I have to admit this is the
first time I've seen one on the EIDE side but it makes sense. (Most are USB
these days and I hardly ever see an internal zip drive any more.) The
solution for them has been to assign it a higher letter and then to go back
into computer management and from there (it appears, really... I wouldn't
make this stuff up...) and set the other drive (sometimes it's an extra HDD
or an external HDD or I've even seen it with an external burner) to the
lower letter. I'm not sure what you'd do if all the letters from F: to Z:
were all taken up. Try, if available, the support options with Microsoft
directly?

Does the BIOS see both drives?

No, only one at a time (zip drive when alone or w/ CD, CD only when zip
disconnected). Thanx!
