Check the manual that came with your motherboard (or the hardware manual
that came with your computer).  3.0GB/s SATA is otherwise known as "SATA
II", "SATA 3.0" and/or "SATA/300".  If it just sez "SATA", it's 1.5Gbs 
"SATA-I" and you either need a controller card or a new motherboard to
use the 3.0GB/s drives.  Sadly some SATA-II drives don't automagically
downshift to SATA-I mode nicely... you may have one of these.

Found out the hard way when I bought 2 VelociRaptor drives'idly,
