Ram already gave the stock "no" answer.  Just a couple of other comments.

Perhaps change your runtapes to "2" so no more than 2 tapes will be used
per amdump run.  Then the 3.8 GB will be retained on the holding disk and
IF you have autoflush set also, will be flushed to the begining of the
next virtual tape on the next amdump run.

A "taperwait" patch was published on the amanda lists about 6-9 months
ago.  IIRC It would not go to the next tape unless there were at least
enough dumps on holding disk to fill "X"% of the tape.  I don't know
the status of that patch with 2.5.0.

JLM indicated he might work on an alternate to taperwait which was more
flexible, but was uncertain when he would get to it.
