    i updated to lion - my system was slow. i bought a hard drive (samsung G3 station) today and backed everything up. then did a clean install of lion - now lion wont recognize my external hard drive anymore.

    i really need those files.

    my harddrive turns on when i plug it in - Lion won't recognize it tho.

    please help

    thank you

    is your external a mac formatted hd? (hfs)
    or a windows one? (ntfs)

    if its ntfs u need an app to make ntfs work

    if its hfs, do you see the hd in "disk utility" app? press repair if u see it. that wont delete your files btw.

    good luck

    I upgraded to Lion - it slowed my system. saved EVERYTHING on my external HDD. (it recognized my hard drive then)
    then did a clean instal of Lion - everything works fine EXCEPT IT WONT RECOGNIZE MY EXTERNAL HARD DRIVE ANYMORE, even though it did previously, when it was just an UPGRADE.

    any help?
