Dave,
Remember that by going from "B" drives to "H" drives you are now writing 3
times as many tracks (128 vs 384) per tape, and 3 times as much data per
cartridge.
Consequently, you will almost certainly have some "marginal" tapes that
would work at the lower density that will now likely give problems.
Every site that we have assisted with such an upgrade has experienced some
number of cartridges that have shown up as bad after the upgrade.
Upgrading Atape will probably not be much help here.
If these are IBM cartridges, remember that these have a lengthy warranty
that you can take advantage of (800-IBM-MEDIA); if they are another brand,
check their warranty policies.
Regards,
-Lloyd
