Answer:
total capacity  = 135,168,000,000 bytes
Explanation:
given data
hard disk divided = 1100 sectors
cylinders = 40,000
block holds = 512 bytes
rotating  rate = 4800 rpm
consider average seek time = 12 msec
to find out
total capacity of this disk
solution
total capacity of this disk are express as
total capacity  = hard disk divided × cylinder  block holds × average seek time ÷ 2
put here value we get
total capacity  =  1100 × 40000 × 512 × 6
total capacity  = 135,168,000,000 bytes
