If this is the wrong forum, my apologies but it's the closest I could find. I'm a serious photographer and do my post processing in Capture NX2 (2.2.4). Sometimes, especially when saving files, it drags on interminably. I have read that one way to speed up NX2 is to create a scratch disk. I'm currently upgrading my HD on my iMac G5 (Leopard) to a 1TB HD. Would it be wise (and efficient) to create a partition on the new HD and use it as a scratch disk? I understand you can't use the boot drive as a scratch disk, but if I partition will I be able toname the new partition something other than Macintosh HD, thus permitting use of a scratch disk?
