Question

a person is suspecting bad sectors on a magnetic hard disk. what are ways in which that disk can be scanned for errors? (choose two)
run sfc in a command prompt
run error checking on the tools tab under properties of a hard drive
run chkdsk in a command prompt
run optimize on the tools tab under properties of a hard drive

Explanation:

• Run Error Checking on the Tools tab under Properties of a hard drive: This is a built - in Windows feature that scans the hard drive for errors, including bad sectors.
• Run chkdsk in a command prompt: The chkdsk (check disk) utility in Windows can be used to scan and repair disk errors. When run with appropriate parameters (e.g., chkdsk /f /r where /f fixes errors and /r locates bad sectors and recovers readable information), it can effectively check for bad sectors on a magnetic hard disk.
• Run SFC in a command prompt: The System File Checker (SFC) is used to scan for and restore corrupt Windows system files, not for checking hard disk bad sectors.
• Run Optimize on the Tools tab under Properties of a hard drive: This is used for defragmenting (re - arranging files on) a hard drive (for magnetic hard drives) to improve performance, not for checking bad sectors.

Answer:

• Run Error Checking on the Tools tab under Properties of a hard drive
• Run chkdsk in a command prompt
