I have a Western Digital My Book 500GB Firewire/USB2.0 External Hard drive. Why this thing doesn't support S.M.A.R.T. is totally beyond me (this is a modern hard drive!!), but Disk Utility and all programs that check hard drive health via S.M.A.R.T. do not work with it.

I've noticed a bit of weird behavior from the thing lately and I'd like to know if anyone knows of any software to check hard drive health on the mac for hard drives not supporting S.M.A.R.T.

Thanks much.

    So in Disk Utility for SMART status it says "Not Supported"? No worries man, I have 2 hard drive that say that too. One is brand new and the other is not all that new. There are no ways that I know of that can do checks on it other then Verifying and Repairing the disk. You can check out Disk Warrior. I have never personally used it, but I hear great things. It is mainly used to repair file system damage, so I am not sure if it can check other things like SMART, but might be worth a look.

    Bad news:
    to my knowledge, there aren't any external hard drives that support S.M.A.R.T. verification.

    Good news:
    S.M.A.R.T. verification isn't really a reliable indicator that you're drive is or has failed. Having witnessed 4 hard drive failures on internal drives in my time, I can tell you, S.M.A.R.T. status wasn't able to predict any of those failures. Basically, S.M.A.R.T. status isn't that smart at all.

    S.M.A.R.T. status is not sent through an USB or FireWire connection.

    Greetings,

    S.M.A.R.T. doesn't work over USB/Firewire connections. Use the drive manufacturers software to check the integrity of the drive in question.

    Cheers,
