It's not possible to just "start over" with a defective disk. If it was defective enough to corrupt the first time, then even if it successfully clears, it will quickly corrupt again. Some of the files may be fixed, but there is no way to fix the HDD itself. Nothing I can say will make an HDD with I/O Device Errors not bad. This is what warranty is for. Was it purchased less than 3 years ago? If so, it should be within warranty.
