Hi:

It's been many years since I needed help with Amanda, but I'm stuck on
this one.  I've had a client+server and a client only box set up for
years, backing up no problem (running amanda-2.4.4).  I switched from a
DLT4000 to a DLT7000 several months ago, as the former was wearing out and
I needed more space.

A colo customer requested that I backup his FreeBSD box, which was built
with only on file system, which is using around 8GB of space.  I built and
installed amanda-2.4.5 without a hitch and amchecks look fine.  However,
I've attempted full dumps 3 times using two different tapes (the last
time, I reconfigured and reinstalled amanda duplicating my other client's
config) and all have failed exactly like this:

These dumps were to tape FULL0.
*** A TAPE ERROR OCCURRED: [[writing file: short write]].
Some dumps may have been left in the holding disk.
Run amflush to flush them to tape.
The next tape Amanda expects to use is: FULL1.

FAILURE AND STRANGE DUMP SUMMARY:
  main.heart /dev/da0s1a lev 0 FAILED ["data write: Broken pipe"]
  main.heart /dev/da0s1a lev 0 FAILED [dump to tape failed]
  main.heart /dev/da0s1a lev 0 FAILED [out of tape]

I'm using this tape type:

tapetype DLT7000

define tapetype DLT7000 {

    comment "DEC/Quantum DLT7000 tape drive, hardware compression turned
off"
    length 35000 mbytes
    filemark 8 kbytes
    speed 5 mbytes
}

TIA for any tips!
