For the few users of Win2000 and Iomega external Zip disk or Ditto tape drives (?as well as certain scanners?), here is something I just ran across on the Microsoft site.
(quote) "This problem occurs because Windows 2000 does not support SCSI commands on a parallel port device. This command set is used by Iomega's tools to access and administrate their removable disk drives."
MS SR-1 for Win2000 is supposed to provide support.
