I use K3CCDTools on my laptop to capture video from my webcam out in the
field. K3CCDTools lets you specify the directory that it saves the video to
(C:\Video, for instance). Seems to me that if you connected an external
FireWire (or any interface) hard drive and Windows maps a drive to it (D:
for instance), you could then tell K3CCDTools to save the video to D:\Video.
Obviously the data from the webcam wouldn't be going straight to the
harddrive. It has to go through the FireWire port then through the
chipset's south bridge and then onto the hard drive. Will that get you what
you want? Remember though that your webcam must support USB 2.0 or
FireWire. Connecting a USB 1.1 webcam (most are) to a USB 2.0 port will not
get you USB 2.0 speed.
