Question

Calculate the total capacity of a disk with 2 platters, 10,000 tracks, an average of

400 sectors per track, and 512 bytes per sector?

Answer 1

`Capacity = 2.048GB`

Step-by-step explanation:

Given

`Tracks = 10000`

`Sectors/Track = 400`

`Bytes/Sector = 512`

`Platter =2`

Required

The capacity

First, calculate the number of Byte/Tract

`Byte/Track = Sectors/Track * Bytes/sector`

`Byte/Track = 400 * 512`

`Byte/Track= 204800`

Calculate the number of capacity

`Capacity = Byte/Track * Track`

`Capacity= 204800 * 10000`

`Capacity= 2048000000` --- bytes

Convert to gigabyte

`Capacity = 2.048GB`

Notice that the number of platters is not considered because 10000 represents the number of tracks in both platters
