Just got my new pc build but cant see my sec hard driver under my computer. was able to see it before update window 7 but cant see it no more i can see it on bio n intel rst try everthing include uninstall the sata controller
you need to use windows drive tools .http://pcsupport.about.com/od/windows7/ht/disk-management-windows-7.htm
or you need to use windows 7 install cd..boot from it and on your new hard drive make sure there a partion and format it. then windows will be able to give it a drive letter. without a partion and format it wont show up in windows.
