40) A hard disk spins at 3000 RPM: it has 1000 tracks, 100 sectors/track, & 1000 bytes/sector, an
average random seek time of 10 ms, and an adjacent track seek time of 1 ms.
a) The average rotational delay will be: 10 ms.
b) The transfer time per track will be: 20 ms.
c) The average count of tracks spanned by a random seek will be: 333.83
d) Display a formula which computes the best count of sectors to skew to minimize the rotational
delay for adjacent-track seeks:
\text{ceiling} \left( \frac{\text{contiguous Track seek time}}{\text{time for 1 rev}} \cdot \text{(sectors per track)} \right)
e) Display a formula which computes the time (in seconds) to read/write a 1E9 byte file located
contiguously on this disk (assuming negligible rotational delays between tracks via skewing):
