Step-by-step explanation:
Given:
Surface = 2
Track per surface = 500
Sector per track = 20
Bytes per sector = 1024
We have to store 50 kb file then, required the numbers of sector:

Then, we have the number of sectors in 1:


Then, the remainder = 50 i.e., sector number
Then, the quotient = 0 i.e., surface number

Then, the remainder = 10 i.e., sector number
Then, the quotient = 2 i.e., track number number
