To check for bad sectors on a drive using the command prompt, you can use the chkdsk command. Specifically, you would type chkdsk X: /f /r, replacing "X" with the letter of the drive you want to check. The /f option fixes errors on the disk, and the /r option locates bad sectors and recovers readable information. After executing the command, you'll receive a report on the status of the drive, including any detected bad sectors.
