Kennedy Tape Drive

[Chris Kringle]

I have a Kennedy Tape Drive Model 9610/9660 being
driven by a Tape Dimenison/ Q-Bus Tape Controller,
this is then plugged into a Microvax II running Ultrix
2.2.

I attempt to create a tar tape using this setup.
Everthing appears to go along fine until I get
to verify the tape I read with a tar -tvf.
If I create the tape at 6250 density I get directory
checksum error.  If I attempt to create the same
tape at 1600 density,  I don't have any problems.
The failure occurs in the same place everytime.

If I try to create a dump tape.  I get synch errors
at the beginning of the tape.  When I do a restore
-tvf.  The tape seems to write O.K.  This produces 
a record length short error in the system error log.   

I have one other clue to this problem.  I have the 
hardware set for TS11 emulation.  The system according
to the error log says that it is a TS05 tape drive.
I have tried various hardware settings and no matter
what it still thinks that it is a TS05 tape drive.
I have a different tape drive that knows that it is
a TS11 tape drive so I am sure that the driver is
setup to handle the TS11.

Please help if you can!
