Hi guys - I purchased two Seagate ST3500414CS to replace the stock HDs in my Tivo HDs that were having S03 errors loading the lineup updates. One of the harddrives was DOA, but the other one seemed to work well for a week or so. Now two weeks later, the working one is back getting the S03 error. Is the other Seagate probably bad as well? Or is there something else going on? We have our Tivos & TAs on outlet timers so they shutdown at night. Could that be contributing to the issues? On another subject, are there other (more modern) 1 TB hard drives that I could try for the Tivo HD? Preferably something that is eligible for Amazon Prime? Thanks in advance!
