My harddisk with the system developed some bad sector, thats why I back it up and restore to a new one. During image backup ATI 10 report a reading error, I click ok the process continue and success. Then I restored the image to a new harddisk, while booting into Windows, it prompt for a disk check, and the result is the harddisk has bad sector, the same number with the old one. I put the new harddisk to another machine, format it, do a disk check and without any bad sector. I restore the image again, the same thing happen, disk check before boot into windows, same bad sector reported. I boot into windows, use the harddisk tool to do a error check. Because it is the system disk, I can only schedule a disk check at next boot up, I restart windows, rescan a few time but unable to get rid of the bad sector. How is this possible?
