3 TB Seagate Only formats out to 2 TB w/ 931 Unallocated and greyd out

Make sure the drive is in GPT not logical or primary. Try downloading easeus partition master to help configure your HDD

It's a limitation both in the MBR and NTFS:

Thank you very much, the link by Cobot was very helpful.
I kind of had a feeling this was the issue.

With Windows 7 and your motherboard there is nothing stopping you from doing a GPT format and using the whole drive, just go back into disk management, unpartition the drive and then repartition but select GPT instead of MBR. If you have 64 bit Windows 7 you could even boot from it, although with that motherboard it would be a crime not to have an SSD.  

Oh yeah great read if I was a frickin engineer.   LOL. So how does one open up the rest of the drive to write on? Besides who partitions their drives anymore? The last couple of times I re-installed WinXp Pro it asks to partition I say NO.
What do I care if there is a recovery copy of my OS installed? I just grab my files and stuff the disc in and re-boot/reinstall? Please enlighten me.

Go into your start menu, right click on computer, select manage. Then select disk management. Right click on the disk on the lower list, the right side where the color bar is located. Choose delete volume. If you have several partitions on the disk, delete them all. The it will have a black stripe and say unallocated. Right click again on the unpartitioned space and convert to a gpt disk by selecting that choice. You will then have the full space available to format and use.

You can also do it in the command prompt window using diskpart commands if you like: http://technet.microsoft.com/library/cc725671.aspx

Thank you! That is what I am talking/ err.. writing about. If I could select you as best answer I would. Yet I am not the O.P Thanks again that helped more then that article (which I did read btw)

Glad to hear, it!

Problem solved, I need to thank all that responded as in combination of all suggestions put together I came up with a very very simple solution.
Go into Admin Tools>Computer Management>Disk Management. Off to the left payne you will see your drive numbers ie: 0, 1, 2, 3 etc etc etc. and it may say or probably should say Basic and Online. Find your 3 TB drive and if you have already tried unsing MBR and you have it split up into 1 2TB partition and 1 931GB partition no biggy, go to the right payne and right click, you will get one option that says: Convert to GPT Partitrion. Click on that and you will suddenly have one 3 TB unallocated partition, before you actully start the GPT conversion make sure your split partitions are both Unallocated, if not just delete any that say Allocated oir formatted or whatever. Now after the GPT conversion, right click in the right payne with all the hash marks on the now 3 TB drive and click on simple volume, just as you would an MBR partition step thru the dialog boxes, name the drive if you so choose and accept all the defaults. it will format out to 3 TB and accept data in the windows file system format. Very simple

So with that said THNAK YOU ALL FOR YOUR INPUT
