Disk Activity & Hard Faults

    At about 2AM every morning I get strange behavior out of my Vista 64
    system. Hard drive activity (system drive is 2 X 36GB Raptors RAID 0
    config) goes through the roof, in conjunction with Memory Hard Faults.
    This is being read through the Performance and Reliability Monitor.

    Normally, the computer has 0 - 2 percent CPU usage, about 4 KB/sec hard
    drive activity, and 0 memory hard faults/sec. Then, around 2 AM, hard
    disk activity goes to 40 - over 100 KB/sec and I get up to 60 hard
    faults/sec (I understand this is not actually an error). CPU usage
    increases, but not significantly (AMD AM2 5200). The system even tries
    to access the A:\(Floppy) drive with nothing in it (a noisy operation).
    This is usually 30 min or so into the "operation" (whatever that turns
    out to be).

    Alot of the processes are "svchost (service)", but there are also things
    like games (that are not in use), Open Office, etc - pretty much
    everything on the computer is being accessed by something. I get nothing
    listed in Event Viewer and can find no explanation in Task Manager.

    Is this a function of the Indexing Service, or do I have a problem I
    haven't been able to identify. The computer runs fine otherwise- the
    performance is very good. For what its worth, the Windows Experience
    Index scores 5.9 in all fields except CPU, which is a 5.1. I don't show
    any problem devices or hardware conflicts.

    Any help would be appreciated-

    In Vista, Automatic Defrag, by default, comes into play at 2.00am.

    Windows Defender has a automatic schedule configured to 2 am, if think. Try
    and check the options to turn it off or change it.

    Thanks- it was Defender. I had already stopped scheduled Windows Defrag
    (in favor of Perfect Disk). I appreciate the help.

    The HDD activity shown probably does not isolate streams of data being
    written to/read from the disk.
