    Does Vista (Home Premium, in my case) defrag the hard drive(s) on its
    own, without being scheduled to do so? I know I can manually force a
    defrag, but what about unscheduled defrags? Thanks.

    Hi,

    Actually, by default it's scheduled to go once a week and you need do no
    more. It will occur as a low priority background process automatically. You
    will find this set in the Task Scheduler. As long as you don't remove the
    task or disable the scheduler, it will happen automatically. If you do
    disable either the task or the scheduler, then you will need to manually
    start it when you suspect the drive is fragmented.

    Hi "EW":
    Once you get SP1 installed, when you open the Vista Defrag program you
    will have additional options for defragging your PC. Currently starting the
    defrag program Vista will defrag all hard drives/volumes it thinks needs it.
    With SP1 there is a button to select which drives/volumes you want to defrag
    and start it immediately or set up automatic defragging for just the
    drives/volumes you want to defrag.

    If you open up "Task Scheduler" you should see in the Active Tasks section
    an entry of "ScheduledDefrag". This scheduled task was automatically created
    by the system.

  7. I have a question about that. I recently downloaded the Auslogic Disk
    Defragmentation tool and it found approximately 1,200 files fragmented. I
    am sure that is not a lot considering the computer is a year old and all I
    have used is the Windows disk defragmenter. However, about it running in
    the background...does this only occur when your computer is idle or is this
    when you are performing operations? I question this because I use a laptop
    and I never leave it running, when it is on I am using it and when I'm not
    using it, it is hibernating.

    Thanks for your response!

    As long as the unit is plugged in, the defrag is no issue. If, however, you
    go mobile with it, using the battery, I would suggest disabling the
    auto-defrag, as it will consume power unecessarily by running the defrag in
    the background even when you're running on the battery.

    If you are really concerned about defrag running down the battery, then I
    would suggest that occasionally or somewhat frequently you explicitly run
    defrag while the laptop is on external power, during a time when you are not
    using the laptop. Then there won't be much work that defrag has to do and it
    won't run for long if it starts to run while on battery power alone. Then
    you can leave defrags scheduled task (auto-defrag) alone.

    Hi,

    The default defrag process will run as a low priority process. Obviously it
    will run when idle, but whether or not it runs while in use depends on the
    degree of use. Heavy demands would preclude it, but light ones would not. As
    to how Auslogic will run, I can't answer as I don't use it. I have tried
    some others, perfectdisk among them, and the results are similar to the
    standard process. I personally think that defragging is overrated, and
    casual users will not see much benefit from it. Heavy gamers, video editors,
    autocad users maybe, but casual users do not put that much demand on their
    system and will likely notice little if any difference in response times
    even on a moderately fragmented system.

    I don't see the answer here to a question I have. I'm curious as to why
    the Disk Defragmenter runs on it's own, separate from the time I have
    scheduled? Whenever I look at the last time it ran, it's always at some
    random time not scheduled.

  12. And that "runs automatically" is at 1am every Wednesday.

    It is conceivable that someone might want to use the scheduler to run
    it at a different time, or more frequently.

    Err no. Read the article. Look under "More Information". Defrag runs ALL THE
    TIME when the machine is idle.

    I'll quote it here for you since you seem to be having trouble reading
    it elsewhere, Mr. Know-it-all:

    "In Windows Vista, there are many improvements in the defrag engine
    and in the manageability of fragmentation. By default, Windows Vista
    uses Task Scheduler to automatically keep the hard disk defragmented."

    "You can now use Task Scheduler to schedule defragmentation.
    Therefore, you do not have to manually start defragmentation. By
    default, a task is created and is set to run at 1 A.M. on every
    Wednesday. If the computer is turned off or if the task does not run
    at the scheduled time, the task will run the next time that the
    computer is idle."
