A system includes a controller and a detector. The controller is configured to read servo spirals written on a magnetic surface of a disk drive. The servo spirals are written on the magnetic surface of the disk drive based on seed wedges. The seed wedges are written on the magnetic surface of the disk drive prior to writing the servo spirals on the magnetic surface of the disk drive. The controller is configured to write a servo pattern on the magnetic surface of the disk drive based on reading the servo spirals written on the magnetic surface of the disk drive. The detector is configured to detect, while reading the servo spiral written on the magnetic surface of the disk drive, interference caused by the seed wedges written on the magnetic surface of the disk drive.
