I have a brand new Toshiba 3Tb external that I used once to store by back-ups while I gave my computer a clean state, (after a couple years she was starting to lag.) After backing up, I tested the drive and information on it before formatting my laptop and loosing my only other copy of my files. When I went to put my files back on Windows said the drive is not initialized, when I go to do so, it will not allow any kind of initialization, even with under a terabyte of information on it. I've tried to initialize the drive on multiple systems and 3 different types of Windows (7 Professional, Vista, and XP) and nothing. Now I'm stuck with a clean laptop without any access to the files on the drive. Is it possible for a drive to just become uninitialized on its own? If yes or no, is there any way to retrieve the files still on the drive?
