Came home to the dreaded "Welcome! Powering up..." screen on my TiVo HD (652160) Reboot, no luck... it would just hang on that screen. Left it unplugged overnight, tried in the AM, got as far as "A few minutes more...", then it cycled back to "Welcome!" and didn't get any further. Figured it was the hard drive gone bad. Got a new WD10EVDS, and intended to use WinMFS. However, hooking up my old TiVo drive to the PC didn't work... my PC reported it failed and wouldn't mount it. I figured that at least confirmed it was a hard drive issue. Since it was dead, I did some reading and discovered the InstantCake option. Downloaded and burned the ISO for 652's, then used it on the brand new WD10EVDS. The uncompress & restore reported successful, no problems. It told me to put the new drive in my TiVo, so I did... And I get the solid gray screen about 10 seconds after the Welcome! screen. One green LED, no opportunity to kickstart. Unplugged the new drive and popped the old one back in, just to see what would happen... it continued to hang on Welcome!, but never went gray. So I figure it's something to do with the hard drive, I just don't know what. Any ideas? Did I stupidly miss a step somewhere?
