I don't have time now to review your Ralph's) text. Beyond <<>> have you
intentionally made technical changes not included in the previously accepted

As far as <<>> is concerned I disagree with << PREVENT ALLOW MEDIUM REMOVAL
(...),>> By specific committee decision these commands are to pass through
> PREVENT ALLOW MEDIUM REMOVAL is not described in the SPC. The removal

<< the next command from
each initiator shall be terminated with CHECK CONDITION status
and the sense key shall be set to UNIT ATTENTION>>. appears to be out of
context. Did some text slip on the floor or is it in the wrong place?
