I'd already done that to my second drive, all my data is on "F". I mainly wanted a smaller "C" for imaging. I now have "C", and "S" (1st drive); and "E", "F", and "P" (1T internal); and "X" (external). "S" is what I just moved off "C". I have system managed paging on "P", which seems to work well, and keeps it off my "C" images (with 6 gb ram, 6+ gb was automatically assigned to paging); also have a 500 mb fixed size pagefile on C which is probably bigger than it needs to be. I ended up with this "arrangement" after reading lots of posts here. So far, so good. Just wish I could hide "H", "I", and "J", which I never use.
