LM 17.1




Not sure if this should be posted here, feel free to relocate it to the correct section


I recently started experiencing the following:-


“errors were found while checking the disk drives for /.” (minus the quotes)


I managed to overcome it the same way on each occasion using the “recovery option” then resetting back to an earlier date using “Timeshift”, before this occurs I notice a substantial slowing down of the system (almost hanging) it's as if something is either working in the background or another application is open but hidden, forcing me to “REISUB” then the recovery option.


What options or tools are available to check the drive for errors & repair i.e something similar to Windows Diskcheck, 'nothing too complicated for me please'. I am aware it could be a drive failure but maybe the check would highlight the failing drive.


Thanks in advance

This will give you an abundance of information about your hard drive's health

sudo smartctl -a /dev/sda | less

This will check the whole disk and print out all bad blocks encountered on /dev/sda.

sudo badblocks -sv /dev/sda

Hi NickAu


Thanks for your help.


This is what sudo badblocks -sv /dev/sda found

Checking blocks 0 to 244198583

Pass completed, 24 bad blocks found. (24/0/0 errors)


I don't know if this is a bad sign or good and whether or not they are repairable

or whether they will be overwritten and ignored.


The other command sudo smartctl -a /dev/sda | less came back as Smartctl not found


Thanks once again

Your best option here may be a UBCD. You can obtain it here.  "http://www.ultimatebootcd.com/download.html"


After burning the iso to a CD, you will have a bootable disk with an abundance of diagnostic tools.  The "HDD -> Diagnostics" section has most manufacturers diagnostic utilities on the CD.


There is also an generic test program, similar to the old MS-DOS Scandisk program.  It, however, has minimal repair capabilities.


You can run the HDD manufacturers factory diagnostic right from the disk.  In most cases, it will give you an error code, and tell you if the disk is repairable.



Some of the utilities on the UBCD are capable of irreparable damage to your system.

Only use those tools which are intended to by used on your hardware.

Only use those tools for which you have read the instructions.


When in doubt, ASK!






Sometimes some of the programs fail to load.
