Direction: A hard disk has 63 sectors per track, 10 platters each with 2 recording surfaces and 1000 cylinders. The address of a sector is given as a triple (c, h, s), where c is the cylinder number, h is the surface number and s is the sector number. Thus, the 0th sector is addressed as ❮ 0,0,0 ❯ the 1st sector as ❮ 0,0,1 ❯, and so on.
