The DSECTORSVOL command finds defective disk sectors and lists them in the bad sector table. Sectors in the bad sector table will be recovered at system startup or whenever a volume is mounted. Execute this command when you get read and write errors on the volume.




	CAUTION: Use this command when there is no system activity and when the only user is the system manager.
