   I don't know what motherboard and kernel you are using, but I found 
that using the stock Centos 4.4 kernel-utils package (which includes 
smartctl), smartctl did not work with my Sata II drive. So I downloaded, 
built, and installed smartmontools-5.37, which did. I am also running 
kernel 2.20.1 -- not sure if that is a factor. Plus my sata driver 
module is sata_nv (Nvidia).
