I have a lifetime S3 that has an upgraded 1TB drive that I bought about 6 months ago, formatted from an eBay seller. I just moved the unit from our home gym to the master bedroom and it gets REALLY noisy within a few hours of every re-boot. Not grinding, more like clunking - so I expect it's head seek noise. It's far too noisy to sleep in the same room with it. The seller I bought the drive from doesn't respond to emails and doesn't seem to sell drives any more. Grrrr. Anyway, do I have any alternatives other than to replace this drive AGAIN? This would be the third drive replacement on this unit (first was a $149 "out of warranty repair" directly with TiVo) - lifetime is starting to get pretty expensive. I'd appreciate any suggestions.
