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