The following data refer to a hard disk: number of tracks per side = 600; number of sides = 2 ; number of bytes per sector = 512; storage capacity in bytes = 21 504 000. Determine the number of sectors per track for this hard disk.

Correct answer: (A) 35
Explanation
Capacity = tracks per side × sides × sectors per track × bytes per sector. So sectors per track = 21,504,000 ÷ (600 × 2 × 512) = 21,504,000 ÷ 614,400 = 35.
