You have two solutions. The first is to change out the controller with one from an identical drive and then run a surface scan using either the manufacturer's diagnostic tool or another tool capable of remapping the drive's bad sectors. This is because the new controller will have the other drive's map. Don't forget to redo the map on the other drive when you replace the controller. I did this two weeks ago for a client. The second solution involves a cleanroom and lots of money. HTH, Stheg __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
