I would appreciate some help from anyone who has experience using the
HP DDS drive with standard UNIX backup utilities, e.g. tar and cpio.
I can't seem to write CPIO files to the drive no matter what I do. Here
is a scenario:

  find . -name "foo*" -print | cpio -oB > /dev/rmt/0hn
  mt -t /dev/rmt/0hn rewind
  cpio -it < /dev/rmt/0hn

produces:
   
   foo1
   End of volume
   If you want to go on, type device/file name when ready
    .
    .
After typing a null name to quit, the device is locked and cannot be
used until the tape is removed and loaded again. Any access displays 
the message: "/dev/rmt/0hn: I/O error".

I suspect there may be a hardware problem here, but I'm new to the HP
world and perhaps I'm not using the device correctly. I know that cpio 
file contains 5 files, yet the volume seems to be truncated after the
first. This operation works fine on all other tape drives on my
non-HP systems, including 1/4 inch and 8mm. 

Also, aside from this, I would appreciate a response from those who have
successfully written consecutive files to these drives. I would like
to do this in my backup operations.
