Can't get computer to recognize zip drive

Steve, The 1st thing is to install the correct driver for the 100 on the computer you are using. Is it a Mac or PC? What model of computer is it. I have been able to use the Zip100 disks with an older IIGS and some older Macs (Performa and Mac SE) with no problems. I have had no experience with the PCs. The disks formatted as FAT16 or FAT32 can be read by both Mac and PC. Those formatted for the PC can also be read by Macs if PC Exchange is installed. Mac disks cannot be read by a PC.
Write back with more info to clarify your exact situation.

My Z100atapi Zip drive is recognized by Windows 7, but the old disks are not in a recognized file format. I need to get the old data ..

Greetings - According to Iomega your 100 MB ZIP drive media should be fine at being at least readable (the Iomega software does not work with Win 7) natively by Win 7 and Vista. Since the drive is recognized I suspect the problem is actually the discs themselves.

It turns out that the discs were not very good at long term storage and are notorious enough to have a term referring to the problem as the "Zip Burp" where:

  • A) All files on the disk disappear
  • B) Just Compressed Formats such as JPG, ZIP, CAB, ECT Disapear
  • C) "The Disk Needs To Be Reformatted" message is displayed or
  • D) files disappear as you click them

The only way that I know to find out for sure if your discs are good is if you can find someone with an XP machine that will let you temporarily install your Zip drive (including the latest drivers) and see what happens.

Good Luck,

I have a Zip 250 disk that will not read. When I insert the disk in the external disk drive, it will spin and stop a few times and that's it. When I try to access the disk/drive letter via "My Computer",...

If the disk is unreadable this means that the format or the files extensions on it are not readable in the operation system you use..either are damaged or the disk itself is damaged or it wasn't finalized like it should ...If other disks inserted run ok than the disk it is damaged and it is nothing wrong with the drive itself..When it says to insert a disk this means that it is not seeing the disk at all and it sounds like a drive problem ..but if other disks are ok ..than it is just a damaged disk or in a format unreadable ..beware if it a cd unit ..will not read dvd-es..or if it a dvd kind will not read large dvd-es (dual layer) or blue-ray disks..

Zip drive does not eject the disk and will not power up.

To the left of the Eject Button/Activity Light is a Disk Eject Hole. It will be a very small hole big enough for you to straighten out a paperclip and push in to hit the eject the disk
