Parallel port - Iomega Zip drive - Windows XP - Drive not recognized.

The problem:  My known-good Iomega parallel Zip 100 is not seen.  I should see a drive letter mapped to this device.  This doesn't happen on this PC.
Windows XP - Pro

I have called Iomega and they told me
  - Make sure the Iomega Zip drive parallel is turned on when turning on my computer.  Did not solve the problem
I read Iomega's troubleshooting document on this topic ...   (please read)
   https://iomega-na-en.custhelp.com/cgi-bin/iomega_na_en.cfg/php/enduser/std_adp.php?p_faqid=557

When I get to Step 3 of those instructions, I see this...
   If there is no SCSI controller listed within the Device Manager or if the Iomega Parallel Port Interface driver is not listed under the SCSI controller, you will need to install the IomegaWare software. Please continue with the next step.

Well there IS no SCSI controller listed.
Also, when I look at Ports (COM & LPT) under Device Manager, I see only
   Communications Port (LPT1)  and
   ECP Printer Port (LPT1)

I did (re)install the software - did not solve the problem.

Finally, the drive is NOT a SCSI drive (see link above) - nonetheless, I think it's supposed to show up for Iomega as a SCSI.  Not sure.  Thanks.

My guess about what is going...  I was having issues with my Epson printer (which is on another PC on my network).  (If I remember correctly) Epson support had me do things to Ports in Device Manager.  Therefore, I'm guessing the problem is with the parallel port.  I'm further guessing that NO device connected to my parallel port would work - just a guess.

If a printer connected to the parallel port won't work, then the zip drive won't either.  This software was designed to look like a SCSI drive.  The zip drives have been superceded by high capacity USB flash drives: smaller, faster, more capcity, easier to use.

1.  I know that if a printer won't work, the Zip drive will also not work.  I suppose I should get a parallel printer and connect it as a test.
2.  I know about the smaller, faster USB flash drives.  These, for certain reasons, are the PERFECT drives for me.

Did you installed the IOMEGAWARE drivers? Which release?
The brand new ones - right off their web site.
I think all you will need to do is enter your BIOS and enable Bi-Directional communication for your Parallel port, if Bi-Directional is not available, then choose ECP+EPP for your setting, then save your changes and I think you will be OK. I am not quite understanding why you would need to change parallel ports to connect to a network printer unless it is capturing LTP1, in which case, remove the printer temporarily from the system to see if that is the issue. do know exactly what Epson had you change in regards to settings?
Many, many storage devices are classified and treated as SCSI devices, and will appear as SCSI Devices in device manager, even though they are physically not SCSI.  This includes RAID arrays, IDE drives on a PCI add-on card, some USB devices, and ... yes, most parallel port storage devices (including the Iomega drives).

I'd remove the parallel port drive (e.g. unplug it's cable from the printer port), reboot, then remove the parallel port itself (in device manager), reboot and let the port be rediscovered (hopefully).  Then power down, plug the drive into the port (with power off), and reboot, hoping that the port and drive will be correctly detected.

I agree with onedeej, check your bios settings for the correct port settings.  Also, make sure it's enabled and not conflicting with something else in the system.  You may need to go as far as removeing your printer port from the device manger then rebooting.  
you can always use a separate PCI card for parallel ports if your original is not working

Not sure if the Iomega drivers will support a PCI parallel port card.  While they are "real" parallel ports, they have addresses that are not one of the 3 "standard" parallel port addresses.
Try going to the BIOS and setting it first to just NORMAL and then check if that solves ur problem. If not then set it to EPP and not ECP or ECC+EPP. SOmetimes the extra DMA settings can confuse Windows. You can also try and update ur BIOS if its not new just in case if there is a problem with the BISO itself. If you do not have a floppy drive or you do not use it then disable the Floppy drive from the BIOS and also the Floppy Drive COntroller and then see if that makes things work for you.

Let me know if these settings did not work for you.

Author: Please respond to the suggestions provided so we may offer more advice. ;-)
This is from David Flaschen, the original poster.
The solution (which I learned from Iomega) was ...
  In Device Manager, update the driver for the parallel port from ECP to normal Parallel port.
I did not make any changes to the BIOS (which is still on ECP, the default setting)
Thank you for all your assistance.
If anyone thinks they deserve points, tell me, and I will provide them.

Nifty, I am glad your issue is resolved, is the Bi-Directional checkbox enabled in Device manager too?
Curious because I have clients who actually have ZIP 100 drives, and in case they have an issue with it I would like to know any info possible seeming as to the Iomega website did not provide the appropriate troubleshooting info (they never do) :-(
Normally changing the drivers to Normal LPT is almost equal to changing the parallel port from the BIOS to NORMAL. ECP and EPP are charecteristics that can be changed and accesed via the drivers and are not really hardware dependent. My suggestion was meant for windows to automatically switch to NORMAL drivers which wud have solved ur problem just like it did now.

Changing drivers to NORMAL also did the same thing only u had to do it manually by updating drivers. I would still reccomend to change the port from the BIOS also just in case Windows gets hiccups of hardware/driver mismatch.

If you feel i deserve points based on my answer i'ed appreciate it else i am glad ur problem got solved :-)
