I bought a 500gb western digital external hard drive about a year ago. I have roughly 200gb of data on it. About a week ago I tried to transfer a 4gb file to it and it said there was not enough storage space. I believe this was due to the hard drive not being formatted in NTFS. I am not sure if that has anything to do with my current problem or not. The problem I am having now is when I plug in the hard drive through USB 2.0, I hear the new device sound but the hard drive never shows up in my computer. I have tried removing it and connecting it to an external enclosure and I am having the same problem. I have also tried other ports on my computer as well as other USB cables. It does show up in device manager, and disk management though. I am stumped! Any help would be MUCH appreciated!
