How long does it take to read a disk with 10,000 cylinders, each containing four tracks of 2048 sectors? First, of all the sectors of track 0 are to be read starting at sector 0, then all the sectors of track 1 starting at sector 0, and so on. The rotation time is 10 msec. and seek takes 1 msec between adjacent cylinders and 20 msec for the worst case. Switching between tracks of a cylinder can be done instantaneously?
well the formula is access time = seek time + transfer time
+rotational time
seek time must be the average of 1 and 20, not sure if i m right
and transfer time is according to me 2048*10000
I have no idea what i m doing plz help
