I have looked around for a few days and have not found a solution to my problem. I bought a bolt vox 500gb w/ lifetime service, weakknees and drive failed after a while so I read here that the WD20NPVZ was plug and play and it worked fine for 10 months now it is also dead. I now know I waited to long as the hd is completly dead and I'm stuck on hydra and want to go to an external 3.5 in drive but read something about hydra not working with external drives if you don't go back to TE3. I have an external roswell hd case w/fan, a new 2tb WD Red WD20EFAX 3.5 hd, and the sata cable to go from external hd case to the sata port on the bolt mb. What I don't have is a working drive to downgrade tivo to accept external drive. Am I out of luck or is there a way to get a bolt vox on hydra to work with a new external 3.5 in hd without downgrading bolt? Any help would be greatly appreciated.
