  taper: tape TECH14 kb 10454688 fm 23 writing file: short write

I don't know any tapedrive that has a capacity of 10.5 Gbyte.
(Well to be honest, I only know the cheaper tape drives.)

Is this, just guesssing, a DDS-3 drive with a capacity of 12 GByte?
If yes, could it be that you have hardware compression on?
I would expect to run into EOT at about 11.5 Gbyte.  Putting
compressed files on a tape with hardware compression on expands
the data!

The latest amanda 2.4.4 has a program "amtapetype" that detects
the hardware compression settings of a drive.  (It's time to upgrade
anyway :-)
