(*chuckle*)  Well, it could mean that all your drives are consistently
problematic.  Refer to last week's postings about tape drive cleaning -
the root of so many tape I/O problems.  Dirty tape drives proficiently
spread the gunk throughout your tape complement and to other drives.
Remember also that libraries are not hermetically sealed units - and
computer rooms are far from being Clean Rooms.  If your library is in a
dusty or high-traffic area, consider putting a portable air cleaner
alongside it.
