What is the recommended drive for replacing in tivo?
WD Purple or WD Red?
I bought WD Purple for mine.
WD Purple is the usual choice, but RED is suitable also, but more expensive. I've used hundreds of the purples as replacements in Tivos, and they've been exceedingly reliable.
Tivo upgrades to operate with the new OzTivo EPG, support and service. Over 300 performed here so far. See: www.hillcrest.net.nz
