Sorry, but this really makes no sense at all.

Use dd as explained on http://ffmpeg.org/bugreports.html
(There is no hard size limit, longer samples are 
sometimes useful.)

This seems to indicate that you can even test the 
cut sample but even better would of course be to 
test the cut sample with the application that plays 
the original, uncut file.

Please do not forget to post your failing command line 
together with complete, uncut console output.
