        I experienced some problems with the B1A drives also, but we caused
some of
        our own problems.
        We were running them 23 out of 24 hours every day.
        We cured the problem by going to the E1A and adding more tape
drives.

        The different between the drives is the B1A are 128 track, the E1A
are 256
        track and the H1A are 384 track drives.
        You gain one third capacity for every increment you go up on your
drives.

        We current have a total of 30 E1A tape drives between the open
systems
        backup and the MVS systems native drives.
        Average at the most maybe two calls per year on the same drive
different
        problems never the same.
        We still have a high percentage use per day.

        Hi,

        We are working with a 3494 IBM silo with 4  drives - 3590 type B -
which
        is connected to a RS/6000. As we are having lots of  hardware
problems with
        these drives we think about changing them to 3590 drives type E.
        Does anyone have experience with this type of tape drive ? I`m
mainly
        interested in a kind of comparison concerning performance and
availibility
        between the both types B -> E.

        Thanks a lot
        Martina
