I noticed a large difference in errors between

With unbuffered on, there was no difference between my
input and output file.
With unbuffered off, there were a lot of small errors that
were introduced to the output file.
Is this a known issue, and should I always keep unbuffered
on? gr3.7.6 ubuntu 14.04

If you unceremoniously terminate your flow-graph, there will be data
in 'stdio' buffers that have not yet been committed to the
operating system.
It may be the case, given Gnu Radio's internal buffering mechanism,
that using "unbuffered" all the time is the right thing to do,
unless stdio
buffers offer a performance advantage for an application (Gnu
Radio, in this case) that already does alot of its own buffering.
