If the pagefile is on a 2nd hard drive then no additional head movement occurs on the 1st drive. I've not read anything anywhere that indicates this is different for Windows 7.
I have been doing the same since I went to more than a single drive a long time ago.

This sums it up pretty well as to how to set the pagefile,

You only need to actually fault data from disk to memory is if it's a hard fault. If you have sufficient RAM, you should rarely see hard faults compared to soft faults.

Thank you stormy13. That website tells it like it is. It's hard to outsmart Windows 7. In my opinion Windows 7 handles page filing and ram just great. Just a note. It's hard to break the habit of tinkering with these things like we use to with older systems.

That is what I've found will happen if there are problems whilst having the pagefile on a different disk than the OS.

I have now the pagefile on the C partition. I don't see any difference. Nothing

Considering the paging file is mostly read from, and not written to, you usually would not.

Cannot Set PageFile
My computer has slowed right down lately and I tracked the problem to the pagefile which has suddenly disappeared. When I try to set it back to system managed and click the 'set' button, there is a popup in the system tray that says "SystemPropertiesPerformance.exe - corrupt file". Any ideas?
