Vista Defragmenter and ReadyBoost drive

    I noticed something funny on my laptop last night.

    I have a 2GB SD card which I use for Vista Readboost.

    My laptop is scheduled to perform the Vista Defragmenter at 22:00 each
    Sunday. At exactly that time, the light for the SD card started flashing a
    whole bunch.
    To me, this appears like the defragmenter had kicked-in and was trying to
    defrag the Readyboost drive.

    Now, as the Vista defragmenter GUI is so limited, is there (a) a way I can
    tell if it is defragmenting this drive or not and (b) a way to stop it from
    doing so.

    Surely it's not necessary to defragment this as it's basically one large
    file and also will it not reduce the life of the flash memory considerably by

    Any ideas?

  2. I'm not sure if you can adjust this or not...I've found that for Vista,
    Diskeeper is a good solution, and you can certainly adjust it there. I enjoy
    seeing my defrag work, and Vista's defrag took that away from us.

    I like the idea of using an SD card as a ReadyBoost - thought that only
    worked with USB sticks. Can you notice a difference?

    I'm going to give PerfectDisk a go as that comes highly recommended.

    I'm using the SD card on a Toshiba M5 laptop and it definitely seems to
    improve things - and no USB stick poking out of the back! :)

    Defraggmentation utilizes "Superfetch" (Paging file) - therefore ReadyBoost
    is involved.

    I believe as part of the optimization process for ReadyBoost the device is
    defragmented at specific intervals. Look in Event Viewer at the ReadyBoost
    log under Applications and Services Logs | Microsoft | Windows | ReadyBoost
    | Operational look for Event ID 1017. I suppose when a system defrag is
    started it could also look at the drive used for ReadyBoost.

    ReadyBoost constantly writes to the device, so the defrag is not going to do
    much to decrease lifetime. If you want to see these writes, open
    Reliability and Performance Monitor, expand the disk section and look for
    reads/writes to this file: X:\ReadyBoost.sfcache, where X is the driver
    letter for the ReadyBoost device.

    I use PerfectDisk as well - Good stuff! I heard a rumor that they
    (Raxco) will have something out next Tuesday that will be a huge
    addition to the Vista PC health market. I'll check it out and let you

    Nope not at all. I use an sd card also... You should buy a highspeed 16 gigabyte SD card ^_- a regular SD card is just about as fast as a regular flash drive.... but yeah windows boots super fast since I put in... and some programs start faster as well
