推 just1016:(a)capacity = cylinders x heads x sectors per track 04/22 12:54
2.A multiplattered hard disk is divided into 40 sectors and 400 cylinders.
There are four platter surfaces. The total capacity of the disk is 128MB.
A cluster consists of 4 sectors. The disk is rotating at a rate of 5400rpm.
The disk has an average seek time of 12 msec.
(a) what is the capacity of a cluster for this disk?
(b) what is the average access time before starting data transfer?
(c) what is the maximal disk transfer rate in bytes per second?
想了很久，算不出來XD，高手請幫忙，感謝您。
