This is very odd. I have a 1 gig dos (vfat) partition on my 2 gig scsi
drive and I can do the above test without a problem. I wonder if the
problem is with the aic driver or the msdos file system code.
As to the scsi tape problem, have you tried lowering the bus negotiation
speed on the card for the exabyte. As someone else noted, there's no
problem with Archive DAT's at all. I use one regularly on my 2940.
