This command moves the read/write heads from anywhere on the disk to cylinder 0. Upon receipt of the command, the drive issues a seek to cylinder zero. The drive then waits for the seek to complete before updating status, clearing BSY, and generating an interrupt. If the drive cannot reach cylinder 0, it posts a Track 0 Not Found error.
