    My readyboost cache is deleted when I shut my computer off (I can verif
    by the time stamp)... and recreated shortly after boot.

    Why would it do this on some PC's and not others? I thought SP1 wa
    supposed to fix this. This is frustrating

    Update. Simply disabling readyboost on services will also cause cach
    to be deleted

    Since Ready Boost also supports Ready Boot by recording activity during the
    first 90 seconds after boot so that SuperFetch can do a better job. It may
    be that the cache gets deleted on any system on which you have the
    SuperFetch service enabled.

    ReadyBoot uses the same service (readyboost) generates a different
    directory (also compressed) but it is a separate directory on the hard
    drive.. not USB drive. After 90 seconds bootup, Vista deletes the old
    readyboot cache, because it makes a new one for the next boot.

    The Readyboost usb cache is given a per session key. And I guess thats
    why it deletes the cache before readyboost shuts down. Still, I want to
    know why some users are reporting that their cache is persistent and
    mine is not. I am going to try to force it not to end the session when
    readyboost service shuts down... or force Microsoft to make an option
    for advanced users.
