So i have a few WD Blue drives that i am scanning over and formatting to use on future projects. If i do the windows CHKDSK it shows my drive is fine and no errors at all. However if i run the WD Lifeguard utility one of my drives makes it really far into the scan and then stops saying it has found bad sectors. Im just confused how CHKDSK says everything is fine but the WD utility is telling me otherwise. Also does anyone has any good recommendations for free hard drive repair utilities?
