I'm trying to set up a SATA WD Green 500 GB in a litle older system that has SATA conections built in to the mother board. I see on the boot up it recognizes the drive properly. When I go to install the drive I get can't recognize or there is not any HD to install. I have two similar systems and it fails on both of them. I set the bios to auto detect and change from IDE to a legacy setting on on of the bios to no avail. I even try just to load XP Media in hopes that it will recognize the drive and again It doesn't detect a hard drive either. I ran the diagnostic and everything checks out fine. I try and download the new installation and burn it to a CD and one computer won't pick it up and the other wont boot from the CD ROM I'm pulling my hair out because it seems we are getting less support than usual after they sell their product. I can't believe I'm the only one with this problem.
