this helps

Depends on how you copy the files.

If you mount the floppy first, before the copy, you get a error message on the mount command.

if you just copy a file to a device like cp <file> /dev/fd0/<file> you get a error message on the cp command.

You can test the exit-code of the last executed command, like

if [[ ! $? = 0 ]]
then
echo "error occured"
else
echo " no error"
fi

where $? stands for the exit code.
