My internal HDD can be seen in the BIOS but not the disk manager

[dominomino]

I am unable to see my 1TB WD internal HDD in the disk manager even though i can see it in my BIOS.
I have tried changing the SATA cable and that didn't fix the solution. I have also tried the method in this post, http://www.tomshardware.co.uk/forum/265764-32-guide-installed-disk-system , and still cannot see it.
Any help will appreciated

One possibility: Many BIOSs have a screen where you need to "Enable" each of the SATA ports that you are using. The drives are visible in BIOS, but not in Windows until you enable the port in the BIOS.

Does the drive spin up? Sometimes the drive is configured to Power Up In Standby (PUIS).
