I second Quartz's suggestion.
Just download a live linux cd, such as:
along with checksum files:

Once you burn it to dvd, boot it, and use the gui to launch a terminal 
(icon for it is at bottom left bar).

then you run
su -

then you insert the usb stick.
Assuming there is only one HD in the machine, the stick will be
named /dev/sdb  If more than one HD in the machine, say 4 HD (sda, sdb, 
sdc, sdd), then
the stick will be sde.


dd  if=/dev/zero of=/dev/sd?  bs=1M
where ? is b or c or d ...etc depending on how many HD's you have in the 
You do not need to specify the count, because dd will stop when the 
stick is full of

Once done, unplug the stick, and reinsert it.

then run the command fdisk /dev/sd?  (? as explained above)

create 1 partition.
set it's type to whatever you want. I usually use the letter c as the type
to mean fat lba.

To finish, type the command w  to the fdisk session
and you are done.

Now type fdisk -l  /dev/sd?

and you will see the drive has 1 partition.

now create a filesystem on your drive:

mkfs -t vfat /dev/sd?1   (again ? as explained above).

type the command
and the dvd drive will get ejected.
press the return key to boot into your normal HD.

The stick is now useable and mountable.
