Tapeheads,
I wonder if we should protect the programmable early warning from being 
set to too large a value.  Should we add some statement like the following 
to SSC-4?
If PEWS field of Device Configuration Extension mode page is set to a 
value larger than the tapes capacity, then the Mode Select should be 
rejected with ILLEGAL REQUEST, INVALID FIELD IN PARAMETER LIST.
Thanks,
