I'd like to know how I can check the hardware status, especially the disk drives.
I've tried smartctl, but I get this:
[~]# smartctl -t short /dev/sda
smartctl 5.43 2012-06-30 r3573 [x86_64-linux-2.6.32-379.22.1.lve126.96.36.199.el6.x86_64] (local build)

SMART Disabled. Use option -s with argument 'on' to enable it.
Any other suggestions ? I would also like something that would notify me if something is about to crack.
