I've got a Western Digital Harddrive that is acting up. First, I cannot get either my Macbook or my Mac Pro to read it. It powers up, the blue light comes on, I can hear it spinning... and spinning,... and Spinning. When I moved it from my Macbook to my Mac Pro, I got the same thing, except that not only did the HD not work, all of a sudden my keyboard and wireless mouse (the receiver for which is plugged into a USB port on the keyboard) both stopped working. When I did I hard restart (by holding down the power button until the lights all went off, and then starting it again), everything works fine. (I've unplugged the offending HD when I do this). 1) Any idea what the odds are of fixing the HD? 2) Any idea why my USB Keyboard and wireless mouse would be effected? Thanks!
