Chris-

I can't imagine how one would mount an unpartitioned drive, unless it 
(the machine) automatically partitioned the drive for you, which is a 
bad idea, since it could lead to good data being lost if the machine 
made a mistake and tried to 'help' by partitioning a good drive.

What I did was install the fdisk and mkfs.msdos commands into my LTSP 
root (I have debian sarge, so I was able to just copy the sarge files 
over).  The first thing I did was run fdisk on the terminal and 
completely remove all partitions on the thumb drive, and create a single 
FAT16 partition, and ran mkfs.msdos on the thumb drive.  I don't know 
what these thumb drive manufacturers are doing, but the partition tables 
on these drives are really crazy.  My Kingston had four partitions, and 
I think all of them had overlapping extents, so it would not mount.  I 
deleted them all and recreated a single partition, and every system 
(Win/Mac/Linux) is happy with it now.

fdisk is a little cryptic at first, but really the only commands you 
really need to know are:
p - display the existing partition table
d - delete a partition
n - create a new partition (use type 6 for FAT16)
w - save changes and exit
ctrl-c - Cancel changes and exit!

I'm sure there is a way to batch fdisk so you could make a script to 
clean a thumb drive and reformat it with a single click, but I have 
never tried this.
