MY Series 3 HD TCD648250B is stuck on "welcome, powering up...". I had a WD 300GB drive here that is known to work. I downloaded WINMFS and ran a copy . It took about an hour and said successful, but when I put in the 300GB, it's the same thing. Welcome, powering up... and after a few minutes, reboot. I took my Fluke to the main power supply connector and got the following voltages while on: Orange 3.07vdc Gray 7.64vdc Red 5.08vdc Yellow 12.43vdc Seems ok doesn't it? Could my hard drive be messed up to a point where making a copy isn't good enough? How do I make a new drive from scratch? Saving my old shows isn't that big a deal, but I want to watch TV tonight!
