It does not have the 1.073GB problem. I've never tried anything
bigger than 4GB in one, because that's all I have SCSI-wise.
The largest DEC SCSI drive likely to have been qualified would
have been the 8GB ones. The 1.073GB problem was fixed by
moving from 6 byte to 10 byte commands (i.e. 21 bits for LBN
to 32 bits for the LBN). This should give a maximum disk
size of 2TB or so. However, the last time I posted this
calculation, someone else claimed that there was a
different restriction in the console firmware. I guess
a few years from now we'll be able to see where the
limit really is.
