Page Faults & Hard Drive access

Hey everyone,

I'm trying to find out about a little quirk that happens sometimes with my laptop.

Pentium-M 1.4GHz

1GB PC2700 DDR RAM

80GB 5400RPM Hitachi Travelstar 5K80

ATI Radeon 9200 Mobility

When I'm stitting at home with my laptop connected to the network and I've transferred files either to or from my desktop, the laptop hard drive will have a very short disk access every second, like clockwork. This access is right in sync with a page fault by explorer.exe every second. The problem goes away after a few minutes, but it's somwhat annoying to have the clicking go on...

I've done all the usual checks for nasties. I've scanned my computer with the following (with all the updates, of course):

NOD32 2.50.19

Trend Micro Housecall Online Scanner

Ad-Aware 1.06 Personal

Spybot S&D 1.4

I've got SpywareBlaster 3.4 installed, and I use Opera for browsing. Added to the fact that I've only got a fairly minimal 16 processes running at startup, I'm pretty sure I don't have anything malicious on my computer.

For the record, I have ResHacked my explorer.exe to remove the search item in the start menu (while keeping search functionality), but I don't see how this would lead to my situation.

Can anyone give any insight as to why this might be happening? I've checked for the latest drivers and BIOS at the Compaq website, and I have everything up to date.

Any ideas or suggestions are appreciated.

Cheers!
