  Intel Core i7-3930K 3.2GHz 6-Core Processor
  Asus P9X79 LE ATX LGA2011 Motherboard
  Seagate Barracuda 2TB 3.5" 7200RPM Internal Hard Drive
  SAMSUNG 840 Series MZ-7TD120BW 2.5" 120GB SATA III Solid State Drive

So, last night I finished my first Pc build and aside from the issue I'm dealing with, things went well. I installed Windows onto my SSD and then connected my HDD after the install was completed. When I booted things up everything was fine, only problem was that my 2TB drive did not show up in My Computer. It's been attached via SATA 6.0, 3.0 and whatever the other normal data plug would be. I've already tried reattaching all of the cables plugged into the drive and I don't really have a fix. In my BIOS menu I don't see the drive in the main Drive area though I do see it listed when I go and look through the boot sections. Not sure what the issue is but would like to know how to go about fixing this.

When hare drives come unformated to a user they won't show up under my computer. Use windows disk management,right click on the new hard drive and give it a drive letter. Some times you have to let windows format the drive.

I actually tried to do that earlier. The drive doesn't show up in there.

Make sure the drive on the intel Sata ports. In the bios make sure the Sata ports are set to achi mode not IDE or raid.

Heh i just went into the BIOS to check on stuff and even though it was already set to ACHI mode, I decided to just switch it off and on. So now that I switched it off and on, i can format the disk in Disk Management. Thanks a lot!

i have the same exact problem right now with the same exact hard drive, i have tried everything to find the prob and now coming here to see you have legit the same exact problems as me i will try the same thing you did truning that option off and on. did you turn the option off and save the settings and boot up then shut it off and turn it on?
