No headers'smartctl' is the command line tool to get info and control the S.M.A.R.T. capable drive.
To start with you would probably want to query the status of your drive. This command will print all S.M.A.R.T. info about the disk.
sudo smartctl -a /dev/hda
(You can figure out what hard drives your have by,
Looking in your dmesg output
Traversing your /proc/ide tree
Or looking in /proc/partitions, this also give the partitions so not every device is is a different device )
Often you will need to turn on the S.M.A.R.T. abilities on your drive. (I am not sure, but I believe once you turn this on it could affect the booting of your computer. I have see hard drives with problems cause PC's to get stuck on the BIOS startup, they get stuck on the BIOS with info about a drive that S.M.A.R.T. sees problems with. So be *WARNED* )
sudo smartctl -s on -o on -S on /dev/hda
These options do
'-s on' turns on S.M.A.R.T. for the drive
'-o on' turns on automatic "testing" (might be better termed "data collection" rather than testing, per the smartctl manpage)
'-S on' turns on S.M.A.R.T. autosave of device vendor-specific Attributes, this on
Then we can use the tool to start a selftest,
sudo smartctl -t long /dev/hda
There are several different tests that can be run,
There is a know issue with sata drives. You need to force the smartmontools to treat the drive as a ata drive, with the -d ata option. There are several -d options to force the smartctl to probe the drive.
Here is some example out with a drive of this type with and without the option.
sudo smartctl -a /dev/sda
