Excessive Hard Drive Activity

I have a Dimension 9200 with RAID 1. I don't experience any of the lock ups that other people have in other threads.
 
However, when I switch my machine on the hard disks trash around for ages (sometimes hours).
 
I've called up the resource monitor and both the CPU and Hard Disk are on 100% frequeceny (not usage, just frequency).
 
The item under the Hard Disk that is causing the most writing is the rather non-descript:
 
Image: System
PID: 4
File: C:\System Volume Information\{a super long alpha numeric code here}
 
Which tells me nothing.
 
Under the CPU it's:
 
Image: System
PID: 4
Description: NT Kernel & System
 
Can anyone help me? It's very audable and very irritating.
 
It does also, not surprisingly, have an impact on system performance.

    File: C:\System Volume Information\{a super long alpha numeric code here}
    This is where System Restore points are stored.
    In Vista System Restore takes up a lot of disk space as it makes a restore point every day.

    The first thing I would try here, (assuming the system is running well ) is to delete all but the most recent System Restore point and see if that helps.
     
    1.Click on Start, All Programs, Accessories, System Tools, Disk Cleanup.

    2.In the dialog that appears choose "Files from all users on this computer".

    3.If User Account Control prompts you to confirm the action, click on "Continue".

    4.If asked which drive you want to scan, choose the drive in which Windows Vista is installed on, and then click OK.

    5.Disk Cleanup will scan your hard drive and then display a list of options.

    6.In the Disk Cleanup window, click on the "More Options" tab.

    7.Under "System Restore", click on the "Clean up..." button.

    8.When asked "Are you sure you want to delete all but the most recent restore point?", click on "Delete".

    9.Close the Disk Cleanup window
     
    NOTE
    It seems to be normal for the hard drive to thrash for a while after bootup, but not for hours :smileyhappy:

    Thanks dunedin for such a clear response, it's reasurring just to know what the System Volume bit it and the Hard Disk activity now makes sense.
     
    I'll give your approach a go when I'm back from holiday.
     
    Thanks again. :smileyhappy:
