I have an HP 35470A DAT drive installed in a cabinet with two 1070 Meg 
drives.  The drives work fine and I haven't had any problems with them 
whatsoever.

When I tested the DAT drive, it would read tapes just fine, but I 
consistently get I/O errors when I try to write anything to the tape.

The error seems somewhat non-descript:

----------------------------------------------------------------------

but it doesn't say what kind of error.

Here's the really bizarre part, I installed a new DAT drive because I 
believed that the drive itself was bad.  The new drive does EXACTLY 
the same thing!

I'm not seeing SCSI errors, so I'm inclined to believe that the DIP 
switches on the drive need to be reconfigured.

I'm running Ultrix 4.3 on a Decsystem 5000/25

Any ideas?
