smartctl -a /dev/<your disk> should show all values. If it shows
something that looks like garbage, it means that the database of
smartmontools doesn't have the correct information yet for these new
drives. I know that for the recently new OCZ vertex 2 and 3 SSDs you
need at least 5.40 or 5.41 and that's pretty new stuff. (I just happened
to install Fedora 15 today and that has smartmontools 5.41, whereas e.g.
Scientific Linux 6 has 5.39).
