Traditionally, UNIX systems have had both block and character devices for everything. But FreeBSD-5.x has made everything a block device, so that rfd0 no longer exists. "The Complete FreeBSD", latest edition, talks some more on this. It used to be that your needed to use character devices for anything that was unformatted or "raw". For example, you could only create a filesystem on a character device, but could only mount a block device filesystem. Thus formatting a floppy would require /dev/rfd0, and a lot of documentation still has this. But formatting /dev/fd0 in FreeBSD-5.x works. David
