This is one of the problems with some of the older AKU's. The newest AKU kitchen have solved most of these problems with the storage card not being recognized. Here is a link to the lastest kitchen thread. I would recommend reading the thread. This kitchen has the newest drivers from the official bell 3.3 rom along with Helmi's newest core components. It has been very stable on my 6700 and I haven't had any problems with my storage card since I upgraded to it.

I hope this helps.
