I started here:
<http://support.wdc.com/product/download.asp?modelno=WD2003FYYS&x=8&y=10>

I entered your drives model number, and got here:

<http://community.wdc.com/t5/News-Announcements/bd-p/Announcements>

That is the link I got when I entered the WDC drive # shown in your dmesg.
That looks like too many choices, and probably is, so I would email the 
support link shown and ask for clarification.  Be sure to use the full 
model number of the drive as shown on the drive or the packaging as its 
possible I blew it with my copy/paste here.

The point is, the stuff is there.  But its easier to find on Seagates site 
I believe.

Cheers, gene
