I am running the latest snow leopard on my MBP. Yesterday, my WD Passport for Mac 500GB that I use for Time Machine all of a sudden gave me a message saying that it was drawing too much power from my Mac’s USB and was subsequently disabled. I then tried to plug in another of my WD Passport 320Gb that had a bunch of movie on it, and now it isn’t being recognized. All of my other externals work, and I’ve tested both USB ports which seem to be working just fine. I’ve tried switching cables, restarting, etc, etc. Does anyone know how to enable these drives so I can recover any of these files? Any help would be greatly appreciated.
