He's back -- Fraggie's back

Discussion in 'Windows Vista General Discussion' started by Fletcher James, Feb 6, 2008.

  1. I posted earlier in the week about a Vista system which hung every night.
    More tracing turned up the fact that when it hangs, dfrgntfs.exe is running
    and taking exactly 50% of the CPU (the max which a single-threaded task can
    use on a dual-core machine.)

    dfrgntfs.exe is the defragmenter for NTFS volumes.

    Yesterday evening, I went into task scheduler, and did everything I could to
    disable this, including turning off Manual & Scheduled defrag runs. I also
    told it NOT to run at next opportunity, if it missed its schedule, and to
    cancel (and force cancel) if it ran for more than 4 hours.

    A bit later, I saw this task running again! It could not be stopped through
    Task Manager (it just wouldn't stop) so I re-booted, and left Task Manager
    as my only running task.

    This morning:
    * ntfsdfrg.exe was running again
    * it could not be cancelled
    * the system was hung (clock unchanged since about half an hour after I

    Does anybody have any idea of why this is happening, or how to prevent it?

    Sorry, I have no solution for your specific defragmenting predicament,
    but in my experience, Vista's defragmenter can be a big headache. After
    I got my Vista infested notebook recently, one of the first system
    maintenance programs I loaded on it was the Diskeeper 2008 defragmenter.
    It offers everything the Vista defragmenter lacks : predictability,
    features, control, and performance.:cool:
