Phil, please clarify.........did you completely replace the B1A drives with new E1A drives, or did IBM convert your existing B1A's to E1A's with an upgrade kit?

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. Philip A.

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
