I have a Western Digital Elements SE Portable External Hard Drive (WDBABV7500BK). I run a Macbook Pro 2010, I am having problems getting my external drive to show up on my laptop. When I plug it in, it is not recognised. Also unable to find it in disk utilities. I have also tried using another cord. Is it possible to reformat the hard drive? The existing data is not important. Thanks,
Have you tried using a Self-powered USB hub - often USB drives can suck a lot of power, even overloading a port to the point where it is powered off until restart. Is that a USB or a Firewire, case? What brand case - and of course other peripherals in that port work, and the drive works on a desktop? If this answer is acceptable please remember to return and mark it accepted.
