hi folks!

need some advice/instruction on the use of 400K floppies
in the 3b1.

i backed up some software onto what i thought were 
properly formatted 400k floppies.  the software was
cpio'd and split into 750-block pieces.  each piece
was copied onto a seperate floppy.

when i went to read the software back in, a "cp /mnt/* ."
left me with a bunch of 640 block files!  (not real
conducsive to good backups :-(

an "ll /mnt" indicated that there were 750 block files there.
a  "du /mnt" indicated that there were 750 block files there.
a  "df -t"   indicated that there were 750 block files there.

however,...

a "wc -c /mnt/*" showed me that the files were only 640 blocks!

(AAAAARRRRRGGGGGHHHHHHH!!!)  okay, so we have some formatting 
problems. (pretty obvious now, isn't it? 1/2 :-)

the following is the line in my format script:

====== start ======
        /etc/iv -i /dev/rfp020 /usr/lib/iv/FD10nl
(and)
        /etc/mkfs /dev/rfp021 792:64
====== end ======

and the FD10nl file looks like:

====== start ======
#sccs   "@(#)iv/lib:FD10nl      1.1"
#       iv description file for 48 TPI Floppy file system disk.
type            FD
name            Floppy
cylinders       40
heads           2
sectors         10
steprate        0
singledensity
$
$
$
0
1
$
$
====== end ======

okay, so what am i doing wrong?

thanks for the help,
