    Since upgrading my HD to a 1 To Samsung Spinpoint M8 1TB 2.5 inch SATA II 13" mid-2010 has been running excruciatingly slow.

    I have found countless threads detailing a fix for this issue on the 2009 MBP by downgrading the EFI firmware to 1.6, but this does not work on my laptop.

    Instructions and files can be found at

    I get a greyed 'stop sign' when trying to boot from the USB key on which I have copied the 'Aluminum_MacBook_Pro_recovery.dmg'. The thread has sugested this is because it only works on the 2009 version and can be found here:

    (It is insanely long)

    I have also found suggestions that changing the hard drive cable could solve the issue ( but again this was on MBP 2009.

    Does anybody have suggestions? I have started a new thread as to focus on the MBP 2010.

    Upgrading to Mountain Lion fixed the issue, computer works like a charm now. First time an upgrade actually makes my computer better.
