So I purchased a WD My Book because it was on sale and it had a 4tb hdd in it. I immediately pulled the drive and put it in my old time capsule that had a 1 tb hdd. Everything on that side is fine. I then put my old 1tb drive into the WD My Book because it would be nice to have a external around. The drive doesn't load up or show in disk util. The mybook chipset shows in System Report but no drive shows up. So I pulled the drive back out and threw it in my MacPro... It shows up so I reformatted it, threw it back in the WD MyBook case and Nothing... Anyone have any idea how to fix this?
