I upgraded my external drive with a new 1T drive, and took the old 500 gig WD and put it on SATA port 3. The BIOS boot screen sees the drive, and I think the Device Manager sees it. Unfortunately, the OS does not show it at all. Other facts, there are two drives on SATA 1 & 2 that are in a mirrored RAID, the mobo is an MSI SLI Platinum. All SATA options are Enabled in the BIOS and I've tried two different SATA cables to eliminate a cabling issue...

What am I missing to see this drive in the operating system (already formatted with data) when the BIOS and DM see the drive fine?
 
If you are using Vista you have to use disk manager to "add" the disk to the OS. Its cont panel, admin tools, computer management, then disk management.
 
I've looked in Disk Management, where is the option to "add" a drive? I need to modify my previous statement, the BIOS sees the drive, the Device Manager does not...
 
Here is the way I do it.

Go to the command prompt

type: diskpart and the console will change
type: list disk (see your drive listed there by size and a number in front of it?)
type: select disk 1 (if 1 is your drive)
type: clear
type: create partition primary
type: select partition 1
type: active (sets partition active)
type: assign (mounts drive in windows with a letter)
type: exit

From there you can see it in windows, right click it, then format since data will be RAW format. You could format from command prompt, but don't know if you want want a specific cluster size.
 
Actually, since someone else might have this issue, my mobo only had 4 SATA connectors... I had to add this drive as a New array, striped, then the OS recognized the drive. A buddy was over, and was able to figure it out in a couple minutes... the funny part, I knew he would do that :)
