Engineering

Suppose the hard disk above has 1024 cylinders, 6 tracks per cylinder, 32 sectors per track and 1KB per sector. The maximum seek time is 450 msec, the time to move between adjacent cylinders is 10 msec, the rotation time is 12 msec and switching between adjacent tracks within a cylinder takes 1 msec. a) If the entire disk was full of data stored consecutively, how much time would it take to read the entire disk if the read/write head is already positioned on the first sector of the first track of the first cylinder of the disk? b) Find the maximum access time (worst case) for 800KB of data not stored on consecutive tracks. Clearly explain your solution/working.
