Naomi has put a hard drive into her laptop and the laptop won't recognize it. Leo says that if the hard drive can't be seen in her laptop, or another computer, there's a very good chance it's dead. Naomi says the drive spins up, though. Leo says that's a good thing, maybe running SpinRite would fix it. But if the computer doesn't see it at all, SpinRite won't help. Time to take it to a pro, but there's a good chance it's just a dead drive.
