another trick you can use in linux with gnome. It takes a minuet though.
1. Destroy all partitions, and remake the MBR.
2. create a single partition the entire size of the disk.
3. get the size of your disk from the file manager.
4. make truecrypt container(s) up to the reported size.
5. copy them to the flash device.
6. Hash both the originals on your HD, and the copies on the flash drive.
If the hashes match, your flash drive is as big as the computer says it is.
