I cannot seem to mount my USB thumb drive in knoppix. I am new to linux and have tried to follow various threads on the boards.

I am running knoppix on a computer that has windows xp and suse 9.0 on a dual-boot hard drive.

when i use the terminal as root, I can see that it sees my usb drive and its number is 3.

when I try to mount it by:

mkdir /mnt/USB (this works ok)

mount -t vfat /dev/sda3 /mnt/USB



I get:


mount: wrong fs type, bad option, bad superblock on /dev/sda3,
or too many mounted file systems


Help.......thanks in advance!

Is the thumbdrive really /dev/sda3? You can check with (as root) fdisk -l (that is a lowercase L).

Maybe I was wrong......here is the output, but I still don't knwo what to do with it.....thanks in advance

Is the thumbdrive plugged in? There is no mention of any 'scsi' devices. If it is not plugged in yet, then plug it in, run the above command again and look for any /dev/sdXX partitions.

Does your thumb drive really have 4 partitions? If so, then you could try mounting as you were trying above, but using the other partitions. For example, mount -t vfat /dev/sdaX /mnt/USB It does, however, seem a little strange that you should get those errors.

I do not think my usb drive has any partitions other than fat32.
The computer that I am running the knoppix live cd from has win xp and suse 9.o linux on the hard drives. are these the partitions?
