I dont know. I dont believe that all ssds have bad sectors. I own 2 ssds(intel 80g gen2 and an intel 40g x25m) and Ive never had bad sectors using intels ssd toolbox. The ssd market has been flooded with new ones and they look tempting with their fast writes but honestly you cannot trust any ssd other than intel. Theres a reason that they are the best. RMA it!
