   Default LM has Disks which is gnome-disks which has a SMART function   
   which can check and self-test.   
      
   But I think the way to go about dealing w/ sector exclusion on a disk   
   you plan to continue to use is to 'start over' and format it, as opposed   
   to trying to 'retro' exclude.   
      
   There are instructions for using badblocks to list them to a file and   
   then use fsck to use the file to exclude them; but I don't know if I   
   like that; doing it that way instead of the format.   
      
   ------------   
      
   Steps to Check and Mark Bad Sectors:   
      
        1. Identify the disk:   
        .   
      
   Use fdisk -l to list all available disks and their partitions.   
   2. Unmount the disk:   
   .   
   Before scanning, unmount the partition you want to check using sudo   
   umount /dev/sda1 (replace sda1 with your actual partition).   
   3. Scan for bad blocks:   
   .   
   Use badblocks -v /dev/sda1 > badsectors.txt to scan for bad blocks and   
   save the results to a file (replace sda1 with your partition).   
   4. Mark bad sectors:   
   .   
   Use sudo e2fsck -l badsectors.txt /dev/sda1 (for ext2/ext3/ext4   
   filesystems) or sudo fsck -l badsectors.txt /dev/sda1 (for other   
   filesystems) to mark the bad sectors as unusable.   
   5. Remount the disk:   
   .   
   After the scan and marking process, remount the disk using sudo mount   
   /dev/sda1.   
   6. Check disk health with SMART:   
   .   
   Use the Disks application (found in the menu under Accessories) to check   
   the disk's SMART data and run self-tests.
