  • Caption: The drive with the controller board removed and flipped over. While the connection to the spindle motor is the rather obvious orange ribbon wire, the connection to the read/write heads and the actuator control is somewhat harder to notice. It's the small rectangle with the writing across it on the lower left corner of the drive, which contacts the two rows of solder pads just below the power connector on the controller board.
