TE16 problem

[James J. Roche]

We have a VAX 11/780 which we are running 4.1 BSD on. We seem to be
having a problem with our TE16 tape drive which we believe may be software
related. The console prints numerous hard errors when we read or write
to the drive. An example is shown below:

tu0: hard error bn9534 mbsr=13080<ATTN,DTCMP,DTABT,MBEXC> er=100000<CORCRC> \
ds=50760<ERR,MOL,DPR,SSC,PES,SDWN>

The reason I believe that it is software (possible the ht driver) is that
we just upgraded a second 780 from 4.0 to 4.1 (no comments please, it
was managements fault, not mine) and the problem suddenly appeared on that
system too.

It is not the tape since any tape we use (new or old) does this. We have
had DEC look at both drives and they can't seem to find any hardware
problem.

Can anyone offer any suggestions as to what the problem or solution
may be. Thanks.
