Using the disk drive specifications given in Exercise 8.8, calculate the time required to read a 10MB file assuming

Data from in Exercise 8.8

A typical disk drive from 2004 has the following specifications. The total storage is approximately 120GB on 6 platter surfaces or 20GB/platter. Each platter has 16K tracks with 2560 sectors/track (a sector holds 512 bytes) and 16 sectors/cluster. The disk turns at 7200 rpm. The track-to-track seek time is 2.0 ms, and the average seek time is 10.0 ms. Now assume that there is a 6MB file on the disk. On average, how long does it take to read all of the data on the file? Assume that the first track of the file is randomly placed on the disk, that the entire file lies on contiguous tracks, and that the file completely fills each track on which it is found. Show your calculations.

(a) The file is stored on a series of contiguous tracks, as few tracks as possible.

(b) The file is spread randomly across the disk in 8KB clusters.
Show your calculations.
