    I was
    hoping Mac OS X came with badsect command since it is based on FreeBSD
    as shown in http://www.manpages.info/macosx/badsect.8.html, but it
    doesn't unless I missed something.

    You can install it but I forget how. I installed xattr a while back.
    I think it was JR who told me how to do it.

    Also, I think all Mac Internal drives implement S.M.A.R.T. which you
    can check.

    all drives implement smart. there's nothing special about the ones
    apple uses.

    That may be true but there appears to be no way to access it on
    external drives. None of the disk utilities I have can read it on
    external Seagate or Western Digital drives.

    that's because smart is not supported over usb.

    however, some chipsets have added their own support, so depending on
    which usb bridge chipset is in your external enclosure and the utility
    you are using to read it, it may be possible. otherwise, you'll need to
    put the drive directly on a sata/pata bus.
