My Windows XP "does" something non stop on my hard drive - about every minute, a short blink (~0.2 sec.) of the disk activity diode, causing the power save options never to work.

This really sucks, I have disabled most of the services (like indexing, logging, page file, system restore stuff, but it still "performs" something very important)

Did you check your processes with Process Explorer? Maybe it can help you to figure out what's going on inside. – Mehper C. Palavuzlar Oct 30 '09 at 10:18
Yes, use Process Explorer to track disk activity. It wouldn't surprise me if this was "normal". – harrymc Oct 30 '09 at 10:57

It could be the search indexer running, that would be my first guess. Here is a lifehacker post on how to disabled the indexer. Searching will still work even with this disabled, it just may take a bit longer.
