You shouldn't try to format a mounted partition. umount it before you run mkfs.vfat. Make doubly certain that you are formatting the correct partition - the one that is 29.0 GB (though when I connected in USB mass storage mode I only get 1 partition anyway):

Code:
Disk /dev/sdg: 29.0 GB, 28995223552 bytes
64 heads, 32 sectors/track, 27652 cylinders
Units = cylinders of 2048 * 512 = 1048576 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Is it safe to navigate through gnome to the drive, right click and format that way?
Depends on whether the gui is smart enough to know that it is mounted and to umount it before formatting.
