Captain: no, partitioning a drive won't help. It must be two physically separate drives. The reason, as Marc alluded to earlier, is disk accesses. As your PC is running and e.g. Premiere is running, it spends a surprising amount of time accessing the disk - disk is where virtual memory is, and there are very few apps these days that will fit into your physical memory, so the app will keep calling new routines from the disk. So the heads on your primary desk are constantly moving just to keep your PC running. Now, if you run a disk-intensive app like video capture, the disk has a whole new set of head accesses to cope with. That's a particular problem in capturing video because, in order to maximise your chances of capturing with no frames dropped, you want the capture to have exclusive access to the read/write heads (and, ideally, to be laying down the capture to a contiguous area of disk) - you don't want the heads also being used to swap virtual memory in and out or load and unload new app routines. So a single, partitioned drive won't work because you're using the same set of heads for everything. HTH.

That is very informative, however do you actually need a seperate harddrive? Might you simply partition as "tribute" suggests? May I have as clear cut an answer as possible please?
Thankyou! You can't get much more clear cut than that!
