Have got a SATA 250 gb drive. All of a sudden the above error meessage appears. Cant get access to the drive (where My Docs r) ans XP wont boot up if drive is connected. Had to disconnect drive so PC will boot up. IS ALL MY DATA LOST in this drive, or can I retrieve some of it. It was partitioned into 3 drives. Any advice or help would be appreciated..
