You might try using 800bpi tapes as well as a simple test (or blank
might work,
since this isn't a Cipher).
The reason is that 1600 and 3200 tapes have a PE burst at the beginning
of the tape
that causes the formatted interface to put out a bit of nonsense when
starting up that
is not there when you use the 800BPI tape, which is NRZI and has no such
detect
burst.
I don't have the specifics, but did run into such a problem with 800 vs
1600 on
a Microdata system formatted tape interface eons ago.
I know that the problems of the Microdata interface probably were unique
to that
system, but think it is worth mentioning. I did see problems on other
systems
when using a blank tape vs recorded, and I suspected it was the lack of the
PE burst that caused them, due to the way the system worked. That was in
using the drives with Overland controllers.
