Found this on Amazon and had to try it. This is designed for slim Type 1 CF slots which isn't really necessary for the Fusion. It fits perfectly and the Fusion was happy to format a 4G uSD that I put into an SD adapter and then into this CF adapter. The Fusion is currently copying the whole HD Volume over to the SD. Even though it's a crappy class 4 uSD it's zipping along pretty quickly. Might go a bit faster with a fast SD card.
Anyhow, with CF cards getting more scarce and rather expensive this provides a nice alternative allowing the use of cheaper and more available 4G SD cards.
