If the ideas offered so far don't fix the problem, then the problem may be with SCSI terminators on the drive. (I've had that happen on two 40 MB drives attached externally to a Classic!) I replaced the terminators with ones from 20 MB drives I was no longer using, and those 40 MB drives have been working fine ever since. That was 5 or 6 years ago.
If your drive is like mine, then the terminators are three tiny "plugs" located near one end of the circuit board on the bottom of the drive. I replaced mine using tweezers. And, yes, it is more than okay to use a Zip drive on your Classic. You can even make it bootable. With more than one bootable Zip disks, you can have one for System 6, one for System 7, one configured for Internet, etc. -- Classic Macintosh Computing http://www.mymacclassic.com --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Vintage Macs group.
