problems with msdos floppies in 5.0

[Eduardo Viruena Silva]

Hello pals!

I'm running FreeBSD 5.0-RELEASE p7.

I cannot mount msdos diskettes, I tried:

	mount -t msdos /dev/fd0 /mnt

I get:

	# mount -t msdos /dev/fd0 /mnt
	msdosfs: /dev/fd0: Input/output error
	#

I thought my diskette was damaged, or my drive broken, or my cable...
I checked everything, I even bought a new floppy drive.  Nothing.

Now, with another computer, a very old one, I made a MS-DOS boot disk, I
used it to boot the computer where the problem is happening and I could
read and write files to my diskettes.

I also tried mtools, and they didn't work either.

		# mdir
                plain_io: Input/output error
		init A: could not read boot sector
		Cannot initialize 'A:'
		#

Any suggestions?

Thanks in advance.
