My computer started beachballing, and eventually became unresponsive. Waited a few minutes, and then decided to do a hard restart. Just like that, the hard drive is gone, vanished. I have a second bootable drive that it eventually booted to, but my main drive fell off the face of the earth. Is it really dead from just that? It won't show up in Techtool or Disk utility. It is a three month old Seagate Barracuda, that has made no odd noises or acting up until now. This just feels so....swift. And cold. I am sad.
