Following a power cut my Tivo started rebooting itself every 5 minutes. Suspecting a HDD failure, I removed the drive (a Samsung HA250JC) and ran Spinrite on it (level 2) to try and revive it. It completed the analysis, reporting no errors/corrections, and I replaced it in the Tivo. When I then tried to reboot the Tivo it wouldn't restart - the green light would flash but nothing was displayed on the TV. I then removed the HDD again and mounted it in a Linux machine. The drive was visible in GParted, but showed as being unpartitioned. Does it look as if the disk is trashed beyond recovery?
