New, Related question...

	I seem to remember a warning once that doing a read on a raw 
device reads in at least the physical record size, i.e. sector on disk or
record on tape, regardless of the byte count you put - so that if you have
a 512 byte buffer and read a tape with an 8K block, you write past the
end of buffer! 

	Is this true?  Does it depend on the device controller?
