I had the same problem using an Easy Drive 80 from DCC Systems.
It also uses a Quantum drive (same as Apple and Jasmine).  Apparently
the DCC drive (and probably the Jasmines) used Quantums with generic
SCSI drivers in the drive ROMs, whereas Apple drives have a
customized version of the ROMs.

This is what I was told by DCC Systems anyway. 

Hope this helps,
Frank
