Definitely what JT says. Keep your second drive free and clear of everything - put your programs on the first drive. Just to clarify: the reason for using a second drive for capturing video is so that that's all the heads do - they're not distracted from time to time by loading new routines into memory, so you avoid the possibility of losing frames while the heads are doing something else.
