Need more work explanation how you solved this?
How long does it take to read one cylinder with 32 tracks, each containing 1024 sectors? Each track should be read one at a time and starting at sector 0. The rotation rate is 7200 RPM. Assume that switching between tracks of a cylinder can be done simultaneously and that the read-write head is already positioned at sector 0.
