It does not support MicroDrive, which is a CFII. CFII cards are bigger. Hence, any CFII card will NOT work with the Kodak DC4800.
That said, the Hitachi card you posted is a CFI card, not CFII, so it should work. YMMV.
Many cameras do not support CFII, partially for battery life reasons, and partially for heat reasons. However, you can actually get the MicroDrive to work in these cameras if you build an adapter, or do what one sick person on the web did and took apart his camera and bent all the metal around the slot to make his MicroDrive fit. Note that his firmware didn't quite recognize the 1 Gig drive size, but it still worked.
Also note that if you get Flash, some cards are faster than others. Do a net search for comparative reviews.
