Yea, I also would like to know if there is over 4Gb version which work with Buddha Anniversary... Was the reason I bought the thing in the first place, but my 16Gb DOM isn't recognized by it, no matter what. If someone could explain why some work and some doesn't? Little disappointed here. Afterall CF HDD speed is exactly the same with native A4000 IDE, so no real advantage for me. Bummer.
