smart self

One of our regular sends us a question:

How can I test if my hard disk is going bad? I see few errors in /var/log/messages file.

I/O errors in /var/log/messages indicates that something is wrong with the hard disk and it may be failing.

You can check hard disk errors using smartctl command, which is control and monitor utility for SMART disks under Linux / UNIX like operating systems.
