    Hello all,

    with some advice I did some tests on my Imac this evening and the Hardware Diagnostic gave me some nice error. the error was 4XXX/1/40000000: "SMC"

    I did this test because I thought the temperature sensor of my HDD was failing since the fan of it is pretty much all of the time on 6000rpm and making a lot of noice.

    Hopefully anyone could help me deciphering this nice error

    SMC = System Management Controller.

    Shouldn't be too serious, though if the SMC totally fails, you may be unable to boot up. Take it to Apple for repair.
