Mac OS X dosen't recognize hard disk

I have replace my cd drive with hard drive (western digital 750gb) using the iFixit guide.

My mac for some reason throws error on any interaction with the hard drive, for example on disk utility (when I tried to create 1 partition of fat) -

When I try to setup BootCamp I get this error -

I have managed to erase the hard drive while booting up to GParted (and GParted successfully formatted), but I want to install windows on it.

Do you have any suggestions? Ideas?
