I have an odd problem. I have a Series3 HD 32hr Model tcd648250B. I have three older hard drives that are 1 tb 1 tb and 240 g. They all boot up fine in the tivo. I am trying to put a brand new wd green 1 tb in this unit. I have tried winmsf copy and backup and restore to the new drive and when I put the new drive in, the tivo first splash screen shows up and never goes any further then this. The lights on the front stay on and never change. I even bought the instant back for this unit and baked the new wd hard drive and have the same effect. I hear lots about power supplies, but the other three older hd's boot fine. I have also tried mfslive 1.4 backup/restore and same effect. Any suggestions?
