I tried to search for this answer but didn't find a response that fit my problem. My question is I defrag my C: drive but it does not fully defrag. If I then make an image of it and then re-install it will I then be able to fully defrag C: drive? Will re-installing the image reformat C: so then I will be able to get a full defrag? My C: drive has been up for almost 2 years so I'm wondering if it's just the course of time that creates these bad sectors that don't defrag.
