    defragmentation questions

    i have a vista home premium with a 138GB HD (82GB full, 56GB free) on an HP pavillion computer. my computer is about 2-3years old.

    1) how long does it take to defragmentation for the 1st time? the last time i did it (and the 1st time, with all the info above, my computer didn't finish even after 12hrs+. unfortunately, defragmentation does not have some loading bar, so i could not tell if the thing just stopped or it was just taking a super long time.)

    2) also, when i did defragmentation for the 1st time, my computer started losing free space! what's going on?

    Hi lorripop,

    I have experienced a similar problem and it turned out to be restore points taking up the space (happens during a defrag in Vista I am told). Try deleting and then rebooting. Regarding the time taken, it did take a long time for me too. But exactly how long will depend on how much fragmentation you have. And since there is no visual display, its difficult to figure anything out. I no longer use the Vista defragger. I changed to a third party automatic defrag program.

    How long is a string?

    12+ hours isn't unreasonable with a reasonably large and/or reasonably
    slow drive. If you have drive activity lights, keep an eye on them to
    see what is happening.

    >2) also, when i did defragmentation for the 1st time, my computer
    >started losing free space! what's going on?
    This is likely an interaction between the defragger and shadow copies
    (which in part is how Vista implements System Restore), Vista's volume
    shadow service isn't always defrag aware and in some cases you may lose
    older shadow copies and/or see some space consumed. This is normal for
    Vista, the space will be released as additional shadow copies replace
    the older one.

    To DaveWarren:

    what do you mean string?

    what do you mean "If you have drive activity lights, keep an eye on them to
    see what is happening"?

    wait...so this is normal???
    and will i regain the space back after my computer has finished defragmenting?

    Re: defragmentation questions

    Hi, lorripop.

    Dave was asking a rhetorical question. :^} But his question does have a
    point.

    You asked how long a defrag might take. Dave asked how long is a string.
    Neither question can be answered without knowing more details: A string
    could be any length from less than an inch to more than a mile. A defrag
    can take from less than a minute to more than a day. Yes, on a large drive,
    with many badly-fragmented files and little free space to work with and with
    a slow CPU, a defrag could take many hours.

    Most computers have a light that turns on when the hard drive is active.
    Experienced users can often tell a good bit about what the computer is doing
    by watching the activity light blink on and off. Like the sound of a car
    engine tells a story to a mechanic's ear.

    Defragmenting generally re-organizes the way that file use space on the
    disk. While it doesn't usually create more unused space, it gathers the
    used space together, leaving larger free areas so that later files can be
    stored more efficiently and more quickly. It often seems to the user that
    the disk has more free space than before.

    ...oh, whoops D:

    well, uhm, well, most of the details of my computer is above... but if it helps it takes... 5 mins to start up the computer?? ._."

    wait what do you mean "low CPU"? ._.

    and does that mean that the space i lost would be regained afterwards?? ._.


    and chkdsk might not be related to this question, but if defragging takes a long time, would i expect chkdsk to run just as long?

    The only details I saw were the total size of your hard drive and the free
    space. With that much (56 GB free on a 138 GB HD), defragging should not be
    slowed down. If you had only, say, 5 GB free, then defragging would take a
    long time. Sorry I overlooked that info in your first post. (All I really
    wanted to do was explain the "how long is a string" rhetoric.)

    Five minutes is longer than it takes to boot most computers, I think. Many
    boot up in less than a minute. But there are many variables from one
    computer to the next. How many applications start automatically? Does an
    antivirus scan run at reboot? Et cetera...

    But, both slow startup and slow defrag could be caused by a sick hard
    drive - or one that needs a better driver. Perhaps the system is having to
    make many retry attempts to read some parts of the disk.

    > wait what do you mean "low CPU"? ._.
    That's "a slow CPU". My copy reads correctly; maybe there was a glitch in
    your newsreader?

    > and does that mean that the space i lost would be regained afterwards??
    > _.
    Not sure what this question means. Defragging works by temporarily moving
    file segments to other places on the disk, clearing out larger free areas,
    and then moving all of the formerly-fragmented file into that space where it
    can now be written as a continuous, contiguous entity. You SHOULD have the
    same amount of free space after defragging as you had before; it's just
    organized differently now. Nothing "lost", nothing "regained".

    > and chkdsk might not be related to this question, but if defragging
    > takes a long time, would i expect chkdsk to run just as long?
    Chkdsk and defrag both work on the hard disk files, but their functions are
    quite different. They each might work slowly on a corrupted or failing
    disk - but for different reasons.

    Has your computer been scanned for malware? Recently?

    Re: defragmentation questions

    To R. C. White: (i'm not going to quote, because now that all these quotes are making replies too long it's getting to be abit of a headache to read them D: )

    oh haha that's ok how long would your approximation . A .

    ok i'm sorry, i'm a computer retard. what does CPU even mean ._.

    during defragging see, i realise that the free space decreases..(like mayb 2-3GB??) after defragging do i regain this space back??

    oh.

    uhh i haven't really got the time to do full scans. i'm having my exams soon and i'm using my mum's computer now...because my mum took away mine OTL
