Summary: They sent me a dud. Good news is that WD's RMA process is second to none, but they sent me a dud! All the time wasted trying to debug my systems only to find out it was my new WD hard-drive was agony. The replacement works fine though. So, am disappointed with WD's QC--it shouldn't have left the factory.
Summary: Upgraded TiVo Romio. Nothing to it. Just a few screws and a bracket. Took the original out, dropped this one in, waited for the TiVo to restart and that was all. Really couldn't have been any easier.
Summary: Works like a champ, have in a Windows Media Center rig used for recording HD TV shows from my silicon dust HDhomerun OTA and a Silicon Dust Prime cable card (card supplied by FiOS) network tuners.
Summary: I purchased this HDD for my new TIVO Roamio with 6 recording channels. I have replaced the existing one with this one and worked like a charm without any special settings. TIVO did everything, formatted the drive, installed the OS automatically and ran the setup. I have it for 2 months now and is working well.
Summary: Tivo Roamio base model upgrade. Hardest part of the entire process was removing the cover. Once installed you will need to go through the set up process. Which is a breeze. No need to format drive. You may want to run a full diagnostic test prior to hard drive installation just to CYA in case you happen to get a dud. Amazon was the seller. I paid $146 plus 3.99 for one day shipping. At this point, I can't recommend this drive enough for your Tivo upgrade.
