4 TB Hard Drive not Registering on Computer

Hello,

I just built a new computer and everything is running fine with Windows 7 Pro with 64 bit. Service pack 1 is updated. My SSD drive is working fine. When I hooked up my 4 TB hard drive it was not showing up in the computer setting. It is connected (BIOS) and working fine.

Windows 7 has not prompted me to do anything with the new Hard Drive.

I right clicked on computer/Management/Disk Management and saw the Disk 1. I then clicked on it and made it GPT and it shows as this now in the Disk Management window. It still says it is "Unallocated" in the window to the right of the Disk 1 box. It also says it is "Online" under that.

When I go to computer it only shows my SSD. I've restarted multiple times.

Any ideas?

Thanks

I am a little curious. Can you please give full details of your 4TB drive, Manufacturer, Model No.etc., so that I can check it on the web?

I am now assuming you have connected it as an internal drive. If it is an external drive please state so.

If it is a new 3.5" drive, it should have come formatted as a GPT initialised drive and should show the full 4TB when you connected to a SATA port in the motherboard without your doing anything. But you said you made it GPT. Was it MBR then? A 4TB drive could not be an MBR drive unless you had taken it out from a 4TB external drive.
So please confirm whether it is an external drive or internal drive and post the screenshots of how the drive looks like in Windows Disk Management and also MiniTool Partition Wizard.

Note: If it is an internal drive, you can initialise it as a GPT and if it shows full 4TB you can partition it as you like. You can have as many as 128 partitions. No necessity to split it into two 2GB partitions.
