I'm sure this issue is out there. But my Seagate 1TB EHDD will not show up at all. It's plugged in, there is power to the drive, but it will not show up inFinder, or in Disk Utility. I had this problem a couple weeks ago, then one day, after 5 minutes of being plugged in, it randomly detected it, and then rans smoothly. My MacBook is brand new, and my EHDD is a couple years old, but hasn't seen much use. Does anyone know what is wrong? Is it just my external drive? Are there any sources you guys know of where I can retrieve the information from the drive?
