Why some External Drives don't show up?
This has happened with my old Win 7 machine and my current Win 8 desktop:
In Windows Explorer, sometime one of my external WD drives (I have 3) will not show up. It's not a specific one, it could be anyone of them. If I reboot, the same ones may show up, or may not, it could be any combination. 2 are USB3 plugged into the correct ports and the other is a USB2 plugged into the correct port. These are the exact same drives I used with my old machine and they did this with the old machine. I don't get it. Any ideas?
