Hi there,
Check the make and model # or your MB, and also check if the firmware is BIOS or EFI. When did you purchase it?
Also go to disk management (right click my computer, manage, computer management and click on disk management in the lower left area.)
If you can, please upload a screenshot of disk management dialog box for us to check on your next post. Also right click on the disk volume (should read Disk 1 or 2) of this new HDD), and click properties. Then on the Volume tab, it will give you important data about this drive. What are the listings for the Disk, Type, Partition style, and capacity and unallocated space?
That should help a lot in determining how the MB and OS see this large drive.
