There are several things to consider here. I assume you are running 64-bit OS in order to utilize the 3Tb. If not I don't think the OS can handle that large of disc. There is a section in "Control Panel" under "format" that lists the steps needed to format. I don't have a 3Tb drive but my 2Tb formatted fine under Windows 7 following those protocols.
Your bios must support (via UEFI and GPT) drives over 2tb to format it as a single volume. Otherwise, you'll need to partition it into volumes under 2tb (3 @ 1tb each works well). It is a 3 platter drive of 1tb per. If your MB is not UEFI capable, check out : http://msdn.microsoft.com/en-us/windows/hardware/gg463524
Hi Randy, It really depends on which system you want to install your drive. Most systems like Windows familly and Apple OS X have options to format the drives. Usually, once you boot the computer up, you'll be able to see the newly added drive in the Computer (Windows) or Finder (OS x). Right-clicking on the newly discovered drive will give you a list of options and one of them will be formatting the drive. If you install the drives in a NAS as RAID, there is a program to help you creating volume (I suggest not to create only one volume with the entire capacity, but keep the volume size to the minimum, it's easy to increase the size of a volume later).
