Cool!
I found the old drive that worked with my Canon camera. It's a Hitachi 2GB Microdrive from 2003. It says CF+ Type-II. So larger, with a CompactFlash interface, boring in comparison.

I'm trying to remember the camera... Canon Powershot S1 IS maybe? It used a lot more battery running the microdrive.
Damn, now I want one just to de-lid one and put it on a shelf. Looks like eBay has plenty of these.
