How do you asure that floppy disks are synchronized with their
buffers (i.e. that the buffers get flushed) before removing the
disks?

I tried the following
	mount /dev/fp021 /mnta
	cp file /mnta
	umount /dev/fp021

and


	mount /dev/fp021 /mnta
	cp file /mnta
	sync
	umount /dev/fp021

and


	mount /dev/fp021 /mnta
	cp file /mnta
	dismount -f

AND ALL OF THESE PRODUCED AN INCOMPLETE COPY of file on /mnta !

.... While on the topic can someone provide a brief synopsis of
all the block and character special files in /dev ? Like what is
the difference between /dev/fp021 and rfp021 etc.  I can't seem
to find this information anywhere. Is there any special
significance to the name /mnta?

Any recommendations on good third party books on SYS V or ksh?

Many thanks in advance.
