Flashed the bios to something relevant. I have two ssds to test, a vertex plus r2 and agility 3, both in ICY DOCK mounts. The front panel HDD lights flash a bit (though that probably doesn't mean much). http://www.newegg.com/Product/Product.aspx?Item=N82E16817994083 Getting in the BIOS is a game, because it shows for about 2 seconds (!), but I found AHCI references in there. I enabled this, though still no HDD existence. Maybe it's something to do with the x7dbu motherboard... I haven't found anything related to x7dbu and ssds. Edit: Hm, maybe this is it: Edit: No, that was not it. Edit: It is most likely the ICY DOCK's fault.
