I'm in desperate need of help...I'm in Hong Kong shooting a show with my HVX200 (w/ 4 16gb cards and my 15" MacBook Pro). I normally set up my camera as a 1394 Host and dump the cards to a firewire drive (which must be powered). I have been doing it this way since I have bought the camera. But, now it simply will not work!!! I can't seem to get the camera to recognize that the hard drive is pugged in (I have brought 4 different HD's and none of them work). I had it working on the first day...dumped all 4 cards and now NOTHING!!! Any ideas???
