Hello all. I have a few questions regarding Swapfiles. First, however here is my configuration: 1) Windows XP Pro (SP3), 3.0 GHZ AMD CPU, 2) 1GB Ram, 3) 3 Hard Drives: Drive C (100GB Programs only - no data), Drive d (250GB IDE 7200 RPM) data and app installation points, Web and SQL Data, Drive E (500 GB Sata 7200 RPM) Data, SQL Log files and edited Video Files, 4) Swapfiles: Drive C: 64mb, dump file only, Drive D: 1.5 GB Drive E: 1.5 GB So here are my queries: 1) Does Windows use the swapfile on a particular drive based on editing (data storage, copy etc). For example, if I am editing say a video file on drive D, will Windows use the Swapfile on that drive to store page fault data? This would seem to be rather foolish as the data is being edited on the same drive as that swapfile. 2) How can I tell Windows to use the Swapfile on a particular drive (say Drive E first or can one? 3) Is there a better way to configure the pagefiles? I ask these questions, because I've noticed at several points during the day that the disk drive light flashes like a banshee on cocaine. Eventually (typically after about a minute or so) it settles down. This happens primarily when I edit video files. I understand an realize that editing video files uses a lot of ram and swapfile, so I don't think we need to beat that to death. I've even upped ram to 2BG - but the same thing happens. The same occurs on a different system (similar in config, except it has dual Pentiums with 4 2 gb ram). So it seems that Windows is going to use the swapfile anyway (which of course we all know). I realize that I can configure Perfom to trap and record all this activity, but what is the reality of that data being accurate? I mean, Perfmon will of course require ram (and swapfile) so would those pieces of data (in particular evaluating the Deltas) be that accurate. So I rambled on, just want to be as complete as I can. Thanks.
