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。 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 218.162.127.152
