    Recently i have installed Lion developer preview 2 Mac Os.
    Due to the fact that it was too buggy i decided to install Snow Leopard... i backed up to Time Machine.

    And now my mac does not recognize external hard drive and keep writing to me that to open it i need to have Mac OS 10.7

    Could you help me with some solutions with my problem ?

    Kind Regards

    Yeah, in the future follow my (or our) advice, and use developer releases of Mac OS X only on a separate machine. Each major version of Mac OS X contains file system changes (that means changes in the kernel), which can result in various "bugs" in prerelease versions and/or in permanent data loss. Prereleases are not a toy.
