S.M.A.R.T. on Gutsy T-61

After my my dismal report on my T-61's SATA performance I've been wondering about whether I have everything tweaked right and I tonight I ran across an entry on Thinkwiki about SMART.

Basically if you install the smartmontools package you get a utility called smartctl that allows you to do stuff like


root@gutsy61:~# smartctl -a /dev/sda

Here is an article that explains all this junk and smartmontools and this runs on FreeBSD too so this is something to consider on that front, too.
