4. to test bad blocks on hard disk on Linux, sudo pv -nb /dev/sda > null or replace /dev/sda with the device identifier of your hard disk.

The errors will print in dmesg (comfortable viewing with command dmesg -TL=always|less -R).

pv may need to be installed as a separate package usually called pv.

It doesn't have a menu entry Menu->System->Hard Disks->"Check bad sectors on your hard disk".

It doesn't even have a menu entry Menu->System->Hard Disks->"Display instructions how to check bad sectors on your hard disk from command line", which I assume would be much easier to implement than the actual menu function, and almost as useful for me.
