The Tivo did not die simply by being unplugged.
I would check the following before replacing the drive.
1) If you have another receiver I would plug it into the same cables and see if it works.
2) I would remove and reinsert the access card
3) Use the Hard Drive manufacturers utility to check for physical errors on the drive.
