The Windows format is probably doing a bad sector scan and testing each and every sector during the format. The Unix newfs/mkfs doesn't perform bad-sector checking, but you can invoke things like the smartmon utilities to perform disk checking later on. > Please understand, I intend only to find the answer to the question > with > this.
