Lightning struck on our block a couple nights ago. My Airport Extreme was fried, along with a couple other things, including my Comcast modem. I happened to have a brand new Airport Extreme in a box that I'd never used, so I plugged that in to the new Comcast modem and all was well with my Wi-Fi. Now Time Machine on my Macbook Air and iMac can't see my WD external drive that I have connected to Airport Extreme for Time Machine backups. It's not available in the Airport Utility either. If I plug the hard drive directly into my iMac it reads fine. Any ideas? Could the USB port on the brand new but old Airport Extreme be busted?
