Defrag refuses to defrag disk.

    I have a disc that Disk Defragmenter won't finish defragging.

    On the first pass it did considerable work but quit with 22% fragmentation
    left. Now when I hit defragment it runs for 30 seconds and spits out the
    report below.

    Nothing in the logs to indicate a error.
    Disc is NOT dirty.
    No 3rd party disk tools have been installed.
    Partition has 54% free space.

    Any ideas why defragmentor won't finish?



    Volume (C:)
    Volume size = 99.99 GB
    Cluster size = 4 KB
    Used space = 45.38 GB
    Free space = 54.61 GB
    Percent free space = 54 %

    Volume fragmentation
    Total fragmentation = 22 %
    File fragmentation = 45 %
    Free space fragmentation = 0 %

    File fragmentation
    Total files = 62,368
    Average file size = 1,024 KB
    Total fragmented files = 4
    Total excess fragments = 105
    Average fragments per file = 1.00

    Pagefile fragmentation
    Pagefile size = 3.91 GB
    Total fragments = 2

    Folder fragmentation
    Total folders = 11,430
    Fragmented folders = 1
    Excess folder fragments = 0

    Master File Table (MFT) fragmentation
    Total MFT size = 91 MB
    MFT record count = 73,921
    Percent MFT in use = 79 %
    Total MFT fragments = 2

  5. I think you're chasing a phantom. While it may appeal to your aesthetic
    sense to have all files on your machine completely contiguous, having
    fragmented event viewer files will not measurably affect the performance
    of your machine. It is very likely that you have already spent far more
    time dealing with this issue than you will ever recoup because the
    machine might run a smidgeon faster.

    If you really insist on having contiguous event logger files then you
    could clear the event log. You could also do this:
    - boot the machine with a Bart PE boot CD
    - copy the three files to a different location
    - delete the originals
    - restore the three files
    You will spend a lot of time in doing this, you will end up with
    a very useful tool (the Bart PE CD) but your machine won't run
    any faster.

    Thanks for the repsonse Pegasus,

    The PageDefrag app mentioned earlier sorted those 3 files out, but they
    weren't what I was concerned about. Its the 45% file fragmentation of the
    45GB of used space on the disk. If it was a few percentage points I'd agree
    with you.

    The fragmented files statistically have to include the (3) 10GB SQL Server
    database files running on the system. Are there any inherent problems with
    degragging these files? Their size maybe?

    Defrags were run in safe mode so SQL Server shouldn't have been running so
    they wouldn't have been locked.

    Thanks for all the suggestions so far.

    Thanks for the help.

    The contig.exe tool on the link provided previously sorted me out.

    cheers again,
