SAMSUNG HARD DISK DRIVE 3 times per region. ( Judge failure by reading not the whole cylinder but servo sector only because it is apt to mistake failure to head failure due to scratch) ② PES Check (PES, RCO, Mechanism) : Compare PES value from the first cylinder starting OD(except MC ),MD,ID region to the 3rd → cylinder.
