William and his Dad built their own computer together. Leo says that's a great project to do together! But his hard drive crashed. He rebooted it and now he can't do anything with the OS. Leo says that it's best to wait. Don't reset because that'll cause the hard drive to spew data across the disk. That could cause the hard drive to become corrupt. Fortunately, William has a backup. So Leo recommends doing a deep, low level format and reinstall Windows. He could try running SpinRite, but that won't solve the corruption of the file system. It'll just double check the physical condition of the drive.
