My S3 has been in a reboot loop for the past week or so, without occasional bouts of working properly. I'm figuring it's the HD. SpinRite gave it a clean bill of health, but I think there's just a logical problem. So, I bought a new 2TB HD and dusted off the original S3 image backup I took using WinMFS (when I bought the S3 a few years back). This is the same backup I used against the 1TB disk that is now having issues. At first I was having problems restoring the backup, getting "error writing media inode 1". But quickly figured I'd better use DiskPart to wipe out the NTFS partition I had temporarily put on this new 2TB HD. After that, WinMFS had no problems restoring my image and asking if I wished to expand (which I did). However, after putting this new drive into my S3, I'm stuck at "Welcome! Powering Up...". It's been stuck there for a good 30 minutes now, so that makes me think it was definitely the HD and not the Power Supply. Does anyone have any pointers?
