I'm prepping up a couple of drives for eBay, but I just wanted to checked them first
Is hdtune fairly sound; neither drives reported having any bad sectors...
Yes. For me it has always found bad sectors when there are any. But I also always use the manufacturers own tools outside Windows as well for peace of mind.
