I was getting grey screens on my TivoHD (probably because I removed the cable cards and was only using the analog cable connection). Before I learned about the analog tuner issue, I removed my external drive to check it for errors. Plugged it into a Windows XP PC and ran diagnostics on it. Seemed okay. Reconnected it to my Tivo, and now it keep getting the "Wrong External Storage Device" error when booting. I'm trying to do KS57, but whenever it reboots (after entering the code), I just get the same "Wrong External Storage Device" screen. I can't get to the GSOD to cleanup the drive databases. Instead when the Tivo reboots, I get the "Almost there..." screen and no diagnostics. I'd really like to re-marry the drive without losing my shows. Any advice?
