    For some reason my iMac is intermittently making the noise as shown in this video. (sorry I'm not sure how to embed a YouTube video here!)

    I'm not sure whether this is actually the hard drive, or something else. Should I replace it?

    Cheers

    That sounds more like a bad fan bearing to me.

    Follow this guide to perform an Apple Hardware test and see what that shows.

    It definitely sounds a lot like a bad bearing, but, spinning hard drives have bearings too. I've heard many an old hard drive with worn bearings make noises like that. Also, it's unlikely Apple Hardware test will show up any error messages on a bad had drive bearing... as long as the disk is spinning and can read and write data, this is one thing SMART diagnostics won't pick up on until it fails completely.

    In any case, if it's under warranty, get it checked out. Bad bearings on either a fan or HD are not a good thing.
