Windows 7: wd caviar green shows up in bios only

using 32 bit home premium Windows 7 installed on 320gb wd. Installed a 500gb wd caviar green .



the bios setup sees it as the 4th drive and the smart NCQ says not supported
transfermode says P10 0

does not show up in devices or window storage under management.

checked 7 compatiable not shown but the box says win 7..

need some help

You don't give us any system information, but here's what pops into my head off hand;
Your BIOS may not be addressing the drive properly, so it can't present it to the OS, so to speak.
Check your BIOS settings and tinker with them a bit. See if that helps.
