harry-
unless you’ve seen something i haven’t, there is no hard drive recorder yet. (but then, there’s no camera yet, either.)
it seems like there are strong indications (nothing official) that firestore, who make these drives for other cameras, are most likely going to be developing one. but it’s all vaporware at this point.
well the other thing you could have been thinking of is the thing panny makes for dumping the p2 cards to hard drive. it’s essentially a portable, battery powered drive that can back up the cards. but it doesn’t connect to the camera. you just haul this thing around (i don’t think it’s cheap either,) and back up your p2’s with it when they fill up.
