Zip disk IDE vs. ATAPI addressing problem

I bought a Zip IDE from a 3rd party vendor last fall and it failed recently with the infamous 'clicking' malady.  it was on the same cable (hence controller?) as my CD-ROM and addressed as a master.  worked just fine.  the CD-ROM is addressed as cable select.  So...Iomega sends me a replacement ATAPI version and I can't get it to work.  I've tried addressing as master, slave and cable select.  Problem is I don't really understand ATAPI vs. IDE.  Do I need an IRQ for ATAPI?  I think I'm out of them but not sure.  Anyone got any suggestions?  Thanks, mark@markx.com

The zip drive should be a master and the cdrom a slave not cable select as this requires a special cable.  Set zip to or cdrom to master and the other one to slave not cable select.  You should have not problems.

thanks wayneb...it seems so obvious now.  the only thing that isn't right is that the hard disk select light is on all the time now.  the zip and cdrom are on another cable.  strange, eh?  any ideas?

This does not see correct for the light to be on all the time, something is talking on primary or secondary channel, Is the primary master setup as a single drive?  Also try to switch the zip and cdrom around, if the zip is the secondary master then make it the secondary slave and make the cdrom the secondary master.  Set bios harddrives to auto and allow the bios to auto detect them, do not use static entrys.  Also test for data corruption on the secondary channel, do so by copying some files to zip drive and make sure you can open them or read them properly.  It is very unlikely that data corruption will occur but make sure anyway.  
There is a hotfix available for windows 95 ide removeable drives the link is,

thanks again wayne.  i swapped addresses around btwn slave and master.  maybe it makes a difference what device is first on the cable...closest to the controller port.  at any rate it works fine now.  thanks for your help.
