The OP has not been back here, but this thread caught my attention as I believe I found some corruption in my Netbook's Prefetch folder. It would not only show looonnng HDD access on boot as drugo described, but at odd times during use, e.g. launching a program, the Netbook HDD LED would illuminate and I'd be "locked-out" of using anything for a couple of minutes. I could move the mouse, but I couldn't do anything with it although if e.g. I did try to run something else (and it wouldn't respond immediately because it was cranking as I said) when the HDD activity was over the mouse clicks responded as if I'd queued them-up, with windows & programs popping-open one-after-another.
Anyway, once when this happened I stumbled-in to the Prefetch dir and noticed that the very large AgGl* files therein had been modified at the exact time I'd had the couple minutes of HDD activity & lockout. On a hunch, I stopped the Superfetch service and moved-out all of the Prefetch files (not however the Readyboot folder), changed my Registry settings for Prefetch & Superfetch to "boot files only" i.e. DWORD of 2, and rebooted, and the problem is gone! Clearly, something in the Prefetch folder was corrupted somehow.
There were two odd things about my Fetch settings, which according to other Windows 7 PCs I have should have looked like this:
Instead of the above, my key had EnablePrefetcher as 2, and EnableSuperfetch as 3, and there was another bizarre entry there called "SuperPrefetch" which was 0. I deleted that (could find NO reference to such a thing anywhere) and put both the other settings to 2, and as I said all is working properly now.
My questions: Can anyone speculate where the "SuperPrefetch" entry came from? Also, what might the implication of my settings being DIFFERENT have been? I can find no discussion of this aspect of the registry key i.e. the difference between Prefetcher and Superfetch and what-if-they-are-set-differently.
