Answer is (D) .

The formatted disk capacity is always less than the "raw" unformatted capacity specified by the disk's manufacturer, because some portion of each track is used for sector identification and for gaps (empty spaces) between sectors and at the end of the track.

Can anyone please explain this in simple and easy language :)

Basically, for a disk to be ready to use , some metadata needs to be stored , which is done by the formatting process .Thats why, fomatted , or ready to use disk, has slightly less capacity than unformatted disk.


"Disk formatting is the process of preparing a data storage device such as a hard disk drive, solid-state drive, floppy disk or USB flash drive for initial use."

Right answer.
