Italo,

is this the card I am looking for:

http://www.amazon.co.uk/Sandisk-ULTRA-II-Compact-Flash/dp/B0002DCDG4/ref=sr_1_1?ie=UTF8&s=electronics&qid=1274074893&sr=8-1

Do you think that it's best, prior to buying this card, that I should install 5.5Beta on my 32 MB, update the H-8000fw and then see if it recognizes the other card I already bought?
