One thing you can do (after backing up any important data on the drive) is to set CrystalDiskMark to view the current sector count as the highest possible acceptable number for reallocated sectors. From the Function menu, select Advanced Features, then Health status setting. Move the slider for reallocated sectors to the right until the number shown all the way on the right is one higher than your current reallocated sector count. That way, it will return to saying it is okay now, but if the count gets any higher, it will alert you again.
