Question

Consider a hypothetical hard drive that has 400,000 cylinders, 8 heads, and 128 sectors per track. Demonstrate, in writing, how you would calculate the total capacity of this drive. Assume a sector size of 512 bytes and express your answer in GBytes, to the nearest whole GByte, as defined in computer Science.

Answer 1

The approximately capacity of a hard disk drive is 195 GB

Step-by-step explanation:

sector = 512 B

Sector per track = 128 = 64 KB

cylinder = 8 * 128 (512 KB)

cylinders = 400,000 * 512 KB = 195.3 GB
