It’s definitely possible to fubar your system if you typo something. I’m using /dev/sdb below, change as needed. This will give you a status of a drive. root@local [~]# smartctl --all /dev/sdb blah, blah SMART overall-health self-assessment test result: PASSED blah, blah Then badblocks to check the health of an unmounted partition. root@local [~]# umount /dev/sdb --or-- if encrypted (change to whatever you have) root@local [~]# umount /dev/mapper/lesdb root@local [~]# cryptsetup luksClose lesdb Then find the block size root@local [~]# blockdev --getbsz /dev/sdb 4096 Finally run badblocks. This stops at the first error. root@local [~]# badblocks -svn -b 4096 -e 1 /dev/sdb (If you have no errors above, you don’t need to run this) This logs all errors to a text file: root@local [~]# badblocks -svn -b 4096 /dev/sdb > badblocks.sdb Notes (on my system, ymmv): badblocks takes approximately 40 hours on a 6TB disk. badblocks takes approximately 45 hours on a 9TB disk.
