Emax

Hi all

I’ve just acquired an Emax 2 rack (2213) and I’m trying to connect a SCSI Iomega 100 zip drive. On the back of the drive I have switched the ID to #5 and it is an ‘auto detect’ 25 pin interface so I presume that does away with the need for a termination switch??
Anyway, it’s connected to the SCSI port on the back of the Emax and when I choose to format a disk I can select drive #5 and the display will show IOMEGA ZDRIVE but then when I try to format the disk, it says ‘MEDIA ERROR’. Also, if I use the drive select button, it says it is not an Emax 2 drive.
I have searched and searched for answers but to no avail. I know the Zip disk is already Emax 2 formatted. Does it matter that the Zip lead is auto detect?
Any answers would be REALLY appreciated.
