How many bytes a sector of hard disk holds
WebConsider a hard disk that uses Advanced Format with sector size of 4096 bytes (4KB), 1000 tracks per surface, 50 sectors per track, five (5) double-sided platters, and average seek time of 8 msec. Suppose that the disk platters rotate at 7200 rpm (revolutions per minute). Suppose also that a block (page) of 4096 bytes is chosen. WebFeb 1, 2015 · Number of sectors per track = number of tracks per cylinder / number of sectors per cylinder = 32, 768 / 4096 = 8 3) What is the total size of this disk I got : Total size = cylinders * surfaces * sectors per track * 512 bytes = 32,768 * 16 * 8 * 512 = 2, 147, 483, 648 bytes = 2, 097, 152 Mb = 2, 048 Gb

WebThe number of bytes inside a sector is fixed, it is always 512 bytes. But the number of tracks, sectors per track and sides (i.e., heads) a hard drive has will depend on the model. … WebWhen file sizes do not come out to an even multiple of the cluster size, additional space must be used to hold the file (up to the next multiple of the cluster size). On the typical hard disk partition, the average amount of space that is lost in this manner can be calculated by using the equation (cluster size)/2 * (number of files).
