hard disk

Question

Consider the following parameters of a disk system.

• Number of cylinders = Ncylinder

• Number of sectors/track = Nsector

• Number of surfaces = Nsurface

• Number of tracks per surface = Ntrack

• Sector capacity = Csector

• Cylinder capacity = Ccylinder

Which of the following is correct to compute the disk capacity of the system?

a) Disk capacity = Nsurface × Ntrack × Nsector × Csector

b) Disk capacity = Ncylinder × Ccylinder

c) Disk capacity = Nsurface × Ncylinder × Nsector × Csector

d) All of the above

Comments

Option a and c seems to be correct as

No of tracks= no of cylinder in the disk

In b option it does not include no of surface so it should not be answer .
