How to monitor harddisk with smartmontools

Now let's install the smartmontools package:

# smartctl -i /dev/hda

# smartctl -i -d ata /dev/sda

SMART Health Status

Let's check the SMART Health Status:

# smartctl -H /dev/hda

If you read PASSED it's ok, but if you read FAILED you have to backup your data now: the disk has already failed or it's predicted to fail within 24 hours!
