I was trying the same thing last night. I was told to do the following:
format: fdformat /dev/rfd0 disk label: disklabel -w -r /dev/rfd0 fd1440 new file system: newfs /dev/rfd0
[I’m now running 5.2.1 on my laptop, and I don’t have a
/dev/rfd0. I’m using
/dev/fd0 instead and all seems well.]
I’ve been told to do the above, then mount it. Then you can treat it like any other file system. Use cp to copy, mv to move, etc.
mount floppy: mount /dev/fd0 /mnt mount DOS floppy: mount -t msdos /dev/fd0 /mnt
The above commands allow you to access the contents of the floppy via the /mnt directory.
and remember to unmount:
Hope this helps.
Quick mount floppyThis tip is thanks to aLan Tait <aLan@fil.net>.
You might have seen the article on quickly mounting the CD-ROM. Well, here’s one for your floppy. First, create a mount point for your floppy:
Then add this line to you /etc/fstab file:
/dev/fd0 /fdd ufs rw,noauto 0 0
With such a line, you can mount/unmount your fdd with just the following commands:
mount /fdd umount /fdd
I’ve been trying to mount a floppy for what seems like years. But I don’t have /dev/rfd0 to issue fdformat against …
So I use su and cd /dev and sh MAKEDEV all
and I get:
mknod: <device>: Operation not permitted
where <device> is about a hundred or so standard devices, including rfd0, da0, ad0, wd1s1, etc.
What’s going on here? Why is root not permitted to use mknod in /dev?
What version of FreeBSD? What security level, if any, is specified in /etc/rc.conf?
I am using FreeBSD 4.4-RELEASE. All I did was:
mount -t msdos /dev/fd0 /floppy
works fine for me.
After I mount if I then unmount and change the files on my windows computer then remount the floppy it still shows the old files – they are stuck in cache – how do I tell it to get the new files from the floppy? I remember there is a command for this but I havent used it in a few years
