I'm sure there are ways for the installation of a new external hard drive on your laptop/desktop to go wrong. Please don't name the obvious ways, like if the USB connection cable gets disconnected from either the laptop/desktop or the external hard drive. The reason why I'm asking this question is because I just recently bought a 1tb WD external hard drive. WD has a VERY good reputation, but I'm still worried that a possible program on my computer might screw up the installation. Is this a possibility for the installation to go wrong? Name as many ways for the installation of an external hard drive to go wrong please.
