For what it's worth:

We have Exabytes here, and we figured Exabytes are Exabytes and SCSI is
SCSI.  'Tain't so, I'm afraid -- we needed to have several Exabyte PROMs
changed out in order to make the Exabytes which were on our Suns (UNIX)
work on our PCs (NT, Windows).  I'm not sure whether it's a hardware or
software in- compatibility (i.e. byte order or OS drivers).

>From what you're describing, it almost seems to be an OS-centric problem.

 * Hmm.  I've never tried the 1742 with an exabyte, but i know it works
 * fine on, e.g. the DAT on sun-lamp...
 * 
 * I could believe it doesn't work -- Exabytes are weird...
 *
