Filling the camera back up, I'll see how it goes.

Strangely enough this did *NOT* work! I'm not sure exactly what happened but the 500mb of stuff I copied on there simply vanished into thin air.

A few snaps actually taken with the camera worked fine, though, and I got 500mb out of it at least.

Note that I could not get it to work at all with my Nikon D80 (which simply shows up as a portable drive) but it did work with my S100 (which shows up as a camera.)
