Sorry if this is in the wrong place but it seemed to fit.
Just recently I've been noticing more and more of those generic "hard drive working" sounds, the sort of faint clicking that's a bit like a geiger counter. This has me worried because when I checked the resource monitor it was constantly accessing games and programs that I usually use, I later read that this was a new feature which searches for patterns in usage and tries to guess what you're going to use next. I disabled it to see if the hard drive quietened down, which it didn't.
After a bit more reading I found another bit of information suggesting that it was the Vista search indexer, again I checked the resource monitor and there it was, indexing away. Now I thought that was odd because surely after so many months of usage and so little change on the system, all the files would be indexed by now, wouldn't they? I turned that off too. Again no change.
After doing a quick once over and deciding that my drive was pretty cluttered with junk and that I've been experiancing some strange oddeties lately, I resolved to do a clean install of Vista and start fresh.
And now I have a fresh install and the drive is still sending the resource monitor charts up and down like a hyperactive child on a bed. The RAM and CPU seem fine so now I'm starting to worry that it's a physical problem with the drive.
Basically, help? Any advice would be greaaatly appriciated.
Small update, after soom more random googling I decided to see if turning off page file would make a difference, I think the noises have stopped but what affect will this have on my system and it's performance in the long run?
Turning off the page file means that you'll only be able to have as much stuff running as will fit in the RAM you have installed. If the system runs out of RAM it will probably freeze or possibly crash.
How much memory do you have?
You can run Task Manager (Ctl+Shif+Esc) and check the "Memory" graph on the "Performance" tab. I'd say that as long as you never exceed perhaps 70-75% even when you're running the most and largest programs that you ever use then you might be fine without a page file. Note, however, that some older programs may refuse to work without one.
Which OS do you have? If you have Vista or Windows 7 you can run the Resource Monitor (Start -> type "Resource Monitor", hit <enter>) and look at the "Disk" statistics to see which process is doing the most I/O.
"0 KB in bad sectors" is a good message, it means that you don't have any bad sectors as far as the file system is concerned. But a better check is to look at the drive's SMART counters using a utility like "DiskCheckup". If the disk controller has detected any bad sectors you'll see a non-zero "Reallocated" or "Pending" sector count.
In Resource Monitor you can click on the "Total (B/sec)" column heading to sort the list of processes by their disk activity. Clicking a second time sorts descending so that the heaviest I/O users will be at the top of the list. You'd want to have a look at this while you're hearing the clicking from the drive.
Is there anything in parenthesis after the name of the "svchost.exe" process(es) that are at the top of the list?
And another question - does your system have a light that blinks while the disk is being accessed? If so, is it blinking or on while you're hearing the sounds?
After all the svchost.exe's (there's a lot of them) is "(LocalSystemNetworkRestricted) followed by 1016 in the PID column the highet of these (again, loads of them) is 16-21 million B/sec write and 277,000 B/sec read.
And the light blinks all the time sometimes it doesn't blink at all, it just stays on.
Additionally, it very occasionally stops the excessive behavior while I'm using a program, though most of the time it just keeps going through it.
Edit: Tried DiskCheckup and I assume these are what you mean:

The SMART data shows no reallocated or pending sectors, so the drive appears to be OK.
There's a lot of hits when you Google "LocalSystemNetworkRestricted" - it looks like a lot of other Vista users have this problem and I haven't seen anyone that's posted a solid solution to it. Many people seem to be blaming it on the SuperFetch service, but others claim that turning that service off doesn't solve the problem.
It's possible that you're seeing pagefile activity due to insufficient RAM, although with 4GB this seems like a stretch. When you run Task Manager (Ctrl+Shift+Esc) what is the amount of memory that's used in the graph on the "Performance" tab?
Is it at around 1.2GB when it's doing a lot of disk activity? If so, the page file won't be the issue.
I'm at a loss to explain the issue. From the threads I've seen (related to "LocalSystemNetworkRestricted"), it seems to be something that a number of Vista users have complained about. I haven't seen any complaints of that type from Windows 7 users, though...
