Our program MacDisk was tested with all types of Zip drives (SCSI, parallel port, IDE/ATAPI and USB, 100 and 250 MB).
The SCSI Zip drives are quite normal SCSI devices and behave normally when instructed to execute the various SCSI commands. If your SCSI bus is heavily loaded, we suggest putting the Zip drive in the middle of the chain and not using the internal terminator of the drive.
The IDE/ATAPI drive behaves like a SCSI drive under Windows 95/98 and NT.
Please note that some versions of the firmware (14D and less) declare the drive
as a floppy drive and not as a disk drive. You can observe this behavior in the
Explorer, since the drives appears as a floppy drive B: and not as a disk D: or
higher. Those drives don't execute correctly all SCSI commands. Please download
our TestScsi utility (length 44 KB). Run it on
your computer and test all commands after selecting the Zip drive. If you can
read data from a Macintosh cartridge, our programs should work. If not, try to
get a more recent model. Any feedback appreciated!
You should also check that the drive is correctly set (Master or Slave), depending on your IDE bus.
When the drive is correctly installed (that is, is not run with the guest utility alone), it behaves like a quite normal SCSI drive.
Under Windows 2000, the parallel port Zip drive doesn't behave any more as a SCSI-like drive (against what happens under Windows 95/98 and NT 4). You should upgrade to current version to access those drives.
We also tested our programs on the new USB Zip drives. Those drives behave
quite normally like SCSI drives and we had no difficulty to read/write/format
disks as Macintosh volumes. Please note nevertheless that those drives are not
really USB drives, since they need their own power supply and they use non-standard
connectors. More, the drive has no connectors to chain other devices.
Under Windows 2000, the USB drives aren't considered as SCSI devices by the system. You should upgrade to current version of MacDisk to access those drives.
We also publish on this site a FAQ on some aspects of using Zip cartridges to transfer data and files between Macintosh and PC.
