Is there a nice easy way to tell where a tape has been?

I'm experiencing about a 15-20% failure rate, over time, in tapes in my
3584 LTO (Ultrium, not DLT).  The tapes that are failing are from varied
vendors, but all are non-IBM tapes.  I'm afraid that one of the drives
is potentially causing physical harm (tapes sent off for analysis have
shown, in some cases, damage after 150ft) but I don't want to have IBM
just replace everthing without having an idea of what I'm after.

What could I do to gather that information?  I could run a nightly
script watching tape activity, of course, and keep that data, but I'm
wondering if Tivoli keeps that conveniently.
