StingMe, yes, I saw those pages-- unfortunately, they don't answer my question. I found a firmware updater that will take the card to v3.2.2 of its firmware, but I wasn't able to find any commentary about what that firmware update does, relative to prior versions, nor about whether this card does or will ever support large drives.
