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).
