Thanks for the reply. I don't have anything unusual running in the background; without installing any programs (right after fresh install) and with no 3rd-party programs running I still see the I/O activity. When I'm logged in there are two instances of csrss.exe running and the one doing all the I/O reads has a session ID of 1 (meaning I guess that it's launched by the user). I created a new temp user just to check and still saw the constant I/O reads. I notice my HDD LED blinking constantly even if I just sit at the welcome screen without logging in.
csrss.exe is the Win32 subsystem. It's strange to have lots of I/O coming from it, but I'm not really an expert on the behavior of that particular process. Do you have any command prompt windows open and doing anything?
What files is it accessing?

I'm not running any security software, I have superfetch disabled, and I have a Radeon 4870 running the latest Catalyst 8.7 drivers (downloaded from amd.com and installed straight from the exe).
it could be superfetch but what security software do you have?cdd.dll is a Canonical Display Driver so what you may need to do is upgrade your display drivers to vista compatible ones.btw what is your video card?

I checked another computer running XP 32-bit and when I move the mouse on it I get the same I/O reads by csrss.exe. So I guess that's a common Windows thing.
However, that computer does not have the constant HDD LED flickering the way I do. I mean if every Vista user has constant HDD LED flickering then I suppose I can ignore it, but right now my worry is that it's indicative of something weird/problematic going on with the OS somewhere. I dunno, maybe it's a hardware issue? The LED doesn't flicker when I'm in the BIOS, maybe I'll try installing Linux at some point and see if it happens there.

Well, it bothers me. I can't say that my machine feels slower since I have no comparison point as it's newly built and very fast in general. If the HDD LED is constantly blinking for no discernible reason then it suggests something I don't know about is accessing my disk (possibly a security concern), which also lessens the utility of having an LED to inform me of disk activity (kind of like someone constantly pulling a fire alarm when there's no fire).
Is it just the flickering light that is bothering you? Or do you feel that the disk activity is making your machine unresponsive or slower?
The list of processes in the disk activity area varies, sometimes it even empties, but when it's empty I still see the LED flickering. I watched the disk activity list for a few minutes with nothing open and sorting according to Read B/min and Write B/min, and the most common appearances were by System. System was writing to various files, often C:\Windows\System32\config, C:\$mft, c:\$bitmap and c:\$logfile. They were almost exclusively writes, not reads. But again, even when the Resource Monitor didn't show anything accessing the disk the HDD LED was still blinking. Incidentally, I disabled the Distributed Link Tracking Client service (which from the description sounded like it might be the culprit).
If you use Resource Monitor and sort by the processes with the most disk activity (sort by Read B/min or Write B/min), which ones are at the top?
