I 100% agree that zip disks are ancient. I just want to get my data off and erase the zip disks on hand.
I had no idea it would be so hard.
Thanks for writing. This is model # Z100P2, identified on the Iomega site as a Zip 100 parallel port drive. I also saw a drawing comparing the backs of the zip 100 parallel port and SCSI drives. The SCSI has switches in the middle of the back, and the parallel port doesn't. So I'm sure I have a parallel port drive, and I hear from the HP support person that I definitely have a parallel port (called printer port LPT1 in Device Manager).
In BIOS, I tried all the parallel port mode choices -- EPP, ECP, and bi-directional mode one by one, uninstalling LPT1 from Device Manager and then restarting HP afterward so XP would reinstall the innards. No luck.
Per Iomega, the parallel port should work provided (in BIOS) the port is enabled, the mode is EPP or bi-directional, the I/O address is 378, and Interrupt is set to IRQ7, and provided (in Device Manager) the Port Settings are "Use any interrupt assigned to the port" and "Enable legacy Plug and Play detection." I did all this, and got zip (ok, poor word choice) for my efforts.
XP is making parport.sys the driver. I see other options (ppa3.inf Guest.inf ppa.inf) but the XP hardware installer spits them out. I asked Iomega support what the driver should be and they had not one clue. If I could locate someone with XP and a working Zip 100 parallel port drive, maybe I could find an answer to that question.
The Ioware support person said he had tried the same drive on his computer running XP, and that he couldn't get it working anyway. Which, in retrospect, would not make him the best candidate for tech support on this issue.
