Which command checks the disk for errors?

You need to check a hard drive for errors from the command line prompt. What command should you use?

A) DISKPART

B) CHKDSK

C) DEFRAG

D) MEM

Answer: B) CHKDSK

The CHKDSK command is used to check a disk drive for errors. The CHKDSK command checks for both logical file errors and for physical drive problems.

The incorrect answers:

A) DISKPART
The DISKPART command provides you with information about the disk partition and hard drive information, but it won’t check the disk for problems.

C) DEFRAG
If your drive is working properly and you need to defragment the drive, the DEFRAG command line utility is the right choice.

D) MEM
The MEM command provides details about memory usage, but no information on the health of the hard drive.
