A hard disk contains 16 platters. The data is recorded on both surfaces of each platter. Each surface has 6000 tracks. A track contains 2,500 sectors and each sector stores 2,048 bytes.

(a) What is the capacity(expressed in Megabytes and Gigabytes)of one cylinder?

(b) What is the capacity (expressed in Megabytes and Gigabytes) of the entire hard disk? You must show your calculations.

The hard disk from Exercise 1 above has the average seek time of 10 milliseconds [ms]. The disk revolves with the speed of 9,600 revolutions per minute.

(a) Compute the average rotational delay(latency time). (b) Compute the transfer time for 1,400sectors. (c) Compute the total disk access time which is the sum of the three times: the average seeks time, the average rotational delay (latency time), and the transfer time for 1,400 sectors. You must show your calculations. Express all the times in milliseconds [ms].
