The only limiting factor, and this holds true for all SCSI drives when
attached to the LaserWriter IINTX, is that the drive must relay information
on its capacity back to the LaserWriter. This information allows the
LaserWriter controller to determine how much disk space is available for
caching and storage and reports this info back to the LaserWriter Font
Utility.
You'll need to get clarification from the drive manufacturer most likely.
