I recently bought a SCSI zip drive but I cannot use the thing. I've tried it with the link adaptor connected to the SCSI port, and the terminator plug on the ZIP port and vice-versa and at best the drive works for about half an hour then the ST cannot see it anymore.
I know that my STE is not at fault because I have tried it on two different ST's (both have working DMA chips as they will work with a 'traditional' hard drive)
