Question

Calculate Hard Disk Capacity

Answer 1

To get the capacity of the disk, multiply the total number of sectors by the sector size. The total number of sectors is 120*200 + 120*240 + 120*280 + 120*320 or 124800, so the total disk capacity should be 124800 * 4096, or 511,180,800 bytes.

Answer 2

Add the sectors together for a 120 cylinder zone: (200+240+280+320) = 1040 sectors

Since there are 4 cylinder zones, there are a total of 4160 sectors.

Multiply the sectors by 4096: 4160 * 4096 bytes = 17.03 MB
