Home Forums Peripherals & Multimedia Peripherals Windows won't read 64GB Flash Drive?

It's formatted DOS but each time I tried it to print photos at a kiosk the stick never showed up. Assumed that XP was so old it couldn't recognize that size flash drive. Then XP was discontinued and the kiosks were always down because there was no support. So they must be using something different now but the stick still does not show up. So I was finally thinking, partition the drive. Can anyone save me several trips to the store by telling me whether that would work and if it will, what is the largest size partition? (I only want to carry one flash drive around with me.)
