Solved 3TB Seagate Barracuda HDD won't format on custom-built PC

February 18, 2015 at 16:20:22
Specs: Windows 7
It is my first build so I am sure I am doing something wrong, but It shows as drive G and shows that it IS allocated, but when I try to format, it tries, then says it was unable to format. My OS is running off of my 250GB SSD, and I have an Intel i7 4790 CPU, ASUS Maximus VI Extreme MB, 16GB of Corsair Dominator RAM, 2x ASUS GTX970 (STRIX) in 2-way SLI. I have tried re-seating it in the quick connect slot that it is in on my case with no change. Any advice would be super useful.

The issue is the capacity of the 3TB drive. The long standing method of MBR can't work on the 3TB drive. You need to use GPT type, if your disk controllers are capable. See the link below or Google GPT versus MBR.

Quick question, is the OS on the C drive?

Always pop back and let us know the outcome - thanks

Yes. Yes it is. The SSD is the C drive.

I will give it a try, but it shows this as a method for formatting SSDs. The one I am having trouble formatting is an HDD. Do you think it will still work?

My mistake but it won't hurt to try it, either Quick or Full Format.

Here is how, stop short of installing Windows.

That's what I was thinking also as I read it. Delete any partitions and reinitiate it as a GPT drive, then partition and format.

You have to be a little bit crazy to keep you from going insane.
