These dumps were to tape Daily001.
*** A TAPE ERROR OCCURRED: [[writing filemark: Input/output error]].
I am getting regularish error as below.
It seems to be related to a long pause in the cycles as the 
last halfcut partition is dumped prior to taping

Here is my tapetype

define tapetype Ultrium {
    comment "Ultrium LTO"
    length 101632 mbytes
    filemark 10 kbytes
    speed 13884 kbytes
}

NB filemark WAS 0 kbytes, and as someone else has just queried -- is
this OK?
I set it up to 10 kbytes to actually 'make a space' 

And no the actual dump size is not bigger than the tape size
(unless I am badly miscounting something...)

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: Daily005.
