1) if the HDD is damaged, quick copy everything off it to another drive so that, when the damaged HDD fails, you still have the files.

2) Do you have another drive with which you can test the USB ports? Is it possible that your usb2 port itself is faulty?

USB 3 ports can provide more power than USB 2 ports. That may be the issue. To test it, you'd either need a powered hub that can deliver out-of-spec power or one of those Y cables that connects an external drive to 2 usb 2.0 ports - one for power and data, one for power only. I've had two drives that needed that cable.
