    A few words of advice please.
    I am wanting to upgrade the hard drive in my late 2009 iMac.
    I understand that the hard drive temp sensor is inbuilt into the hard drive in this model. The make of hard drive in my computer is Western digital and I have the part no WDC WD5000AAKS-40V2B0. So my question is, is there a 1 terabyte WD hard drive that would be a direct replacement for the old one with built in sensor and if so what is its model no please?
    Any help much appreciated.
    Thank you in advance.

    Here is a link to an article that contains a link to the Other World Computing web site purportedly containing compatible hard drives. Maybe it will help.

    If you have trouble with the temperature sensor apparently you can get a drive agnostic sensor that is usually used for the optical drive. You just tape it to the drive and it returns the appropriate signal to the motherboard. Part #922-9229, search for it on ebay.

    Go SSD

    If you are having to replace the HDD then I would go for a SSD. For the small extra amount it will transform your iMac.
    Also add more memory to bring it up to 6Gb and you will feel like a brand new mac... everything will run much faster and be snappier generally.

    Temp sensor then becomes pointless btw.
