Answer Part 2:

A hard disk has four surfaces (that's top and bottom of two platters). Each track has 2,048 sectors and there are 131,072 (2¹⁷) tracks per surface. A block holds 512 bytes. The disk is not "zoned." What is the total capacity of this disk? Show your work. (Hint: what is the relationship between blocks and sectors? Another hint: All of the numbers given are powers of two.)

Part 2: Given the disk in Part 1, how much data can be accessed without moving the disk heads. (That, is, what is the capacity of one cylinder?)
