Question: A 2 5 5 - GB disk has 6 5 , 5 3 6 cylinders with 2 5 5 sectors per track and 5 1

A 255-GB disk has 65,536 cylinders with 255 sectors per track and 512 bytes per sector. How many platters and heads does this disk have? Assuming an average cylinder seek time of 11msec, average rotational delay of 7msec. and reading rate of 100MBsec, calculate the average time it will take to read 100KB from one sector.
