Advertisements I bought a new Roamio Pro in March 2014. It's been running 24/7, that's almost 7 years or 60,000 hours! I noticed recorded shows started to randomly show slight pixelation once in awhile (not bad but catching my attention). After reading these forums I came to my own conclusion it might be the hard drive beginning to act up? I decided to swap it out just in case, and, while apart I cleaned, changed the fan and button CR2032 battery. I checked the internal power supply capacitors and they all look good, so not changing that. It came with a WD Green WD30EURS. I purchased a WD Red Plus WD30EFRX (CMR). I first ran WD Diagnostics Extended mode on both drives, each took 7 hours and they both checked good. Because I'm going from 3TB to 3TB I chose to use a WAVLINK SATA Dual-Bay External Hard Drive Docking Station for a direct 1:1 clone. I used it as a stand-alone device, no computer hookup. The clone took about 7 hours. I'm happy to say it turned out perfect, no loss of anything including pairing. I've watched quite a few recorded shows and no sign of pixelation so far. Maybe none of this maintenance is necessary, but I now have piece of mind my Roamio Pro is good for a few more years. Plus, working on TiVo's is fun! If you know what I mean!
