All, I've read through lots of posts, and the FAQs too many times to count. I'm set on going the 1TB internal upgrade route for my TiVo HD, as everyone says it's the best, but I'm quite conflicted on what drive to get. My options seem to be, in general: HD Deskstar (not designed for DVR, quiet) Seagate (designed for DVR, less quiet) WD (designed for dvr, quiet, soft reboot problem). Seems from everything I've read that the best bet is to go with a WD drive and run the wdidle3 program to disable Intellipark -- OK, I'm willing to. It's here that I have the problem: How am I supposed to choose between the WD10 models? There's the EADS, EAVS, EACS, EVDS, EVVS...is there a difference? Am I better off, since NONE of those seems to be Intellipark-free, just getting whichever is cheapest, or are some of them bad, but others are about the same? I was following prices on the EVDS for awhile, but they seem to have gone up, so I'm back to square one. Thanks in advance!
