Single answer, multiple-choice

Which disk utility provides the best way to improve disk performance?

A.    CHKDSK.
B.    FDISK.
C.    SCANDISK.
D.    DEFRAG.

Answer:
D

Tutorial:
Defragmenting a hard drive reorganizes all the files into contiguous sectors on the disk. This improves disk performance because the system can recover a file in fewer revolutions of the disk.

Both CHKDSK and SCANDISK can identify and correct disk errors, but neither will improve disk access times. CHKDSK is used by Windows NT family platforms, while SCANDISK is found in Windows 9x family of operating systems. Both perform the same function.

FDISK is a disk partitioning utility used in the initial setup of a hard drive. It creates the Master Boot Record required by the operating system. It does not affect disk performance.
