Finding /dev entry of USB disk

[Dotan Cohen]

Alright, even though I've done this before and I've been googleing for
over an hour (and I know that this is real basic stuff) I just cannot
get this thing formated. Why is the device not being seen? I plug the
USB device in, HAL automounts it (sdc), I umount it, and then I'm
stuck:

hardy2 at hardy2-laptop:~$ umount /media/
cdrom/  cdrom0/ disk/   disk-1/
hardy2 at hardy2-laptop:~$ umount /media/disk-1/
hardy2 at hardy2-laptop:~$ ls /media/
cdrom  cdrom0  disk
hardy2 at hardy2-laptop:~$ sudo mkdosfs /dev/sdc
[sudo] password for hardy2:
mkdosfs 2.11 (12 Mar 2005)
/dev/sdc: No medium found
hardy2 at hardy2-laptop:~$ sudo mkfs.vfat /dev/sdc
mkfs.vfat 2.11 (12 Mar 2005)
/dev/sdc: No medium found
