I have a Seagate external hdd that was working awesomely. About a week ago, I dropped it. I rushed into my office to see if it was still working (I didn't expect it to). It worked fine up until yesterday. I used it to logon to my website at work (I have a password manager), then it just disappeared from my "My Computer" list. It's not in the device manager, I've run the "seatools" from the Seagate site . . . I'm at a loss. I'm sure it's because I dropped it, but why did it take so long to quit? Is it something I can fix? It's making a buzzing noise, like it's trying to run the drive, but not able to. My brother thinks it's a *worm* (?) screw/spring that is loose or not attached. Can anybody help??
