Why each option
CHKDSK is the Windows command-line utility that scans a disk for file system errors and can remap bad sectors by marking them as unusable and redirecting data to healthy sectors.
FIXMBR writes a new Master Boot Record and does not interact with sector-level disk health.
CHKDSK /R locates bad sectors, recovers readable data, and instructs the file system to remap those sectors so they are no longer used, directly addressing the reported bad-sector problem. Running it with the /F flag additionally fixes file system errors found during the scan.
DISKPART manages partitions and volumes but does not perform sector scanning or remapping.
FDISK is a legacy partition management tool with no capability to detect or remap bad sectors.
