    Hi. Did search the forum with no luck, so i ask you a little question.

    I have a MBP 15" with a OCZ Vertex 2 128GB. Before installing SL i wanted to secure erase the device, to restore its writing speeds performance to factory.

    Now, i know LION will enable trim to all SSDs. But will i have to secure erase it before doing a clean install, or will the trim function automatically empty cells on my ssd without having to worry about?

    To secure erase it i'd have to re-open the macbook, and i seriously hate those little screws on the bottom (am i the only one btw?).

    Thanks in advance

    Lion enables TRIM on Apple SSDs, not all SSDs. Thus you would have to secure erase before installing SL.

    because i didn't find a working method to unfroze it directly from the macbook... i always hook it up to an old pc i have to secure erase it.

    my bad by the way, didn't know trim was only for apple SSDs.

    Or you could instead try this LiveCD:

    Here is how to use it:

    Boots perfectly in my MBP 2011. Have yet to secure erase my SSD but will try it before installing Lion.
