Can't format Drive in Win8.1?

[Homerboy]

I have a 3TB Seagate that is recognized and formats just fine in my Win7 machine. I pulled it out and put into a Win8.1 machine and I can't do anything with it.

This is how disk manager sees it:

It was ONE parition when I pulled it out of the Win7 machine.
As you can see too, I can't re-partition or format or anything.

Help?

There is only the 1 account on the machine.

2 different machines.. 2 different bios(s)..
MBR vs GPT

Thats fine... though I guess I dont see how that's a problem -- I've shuffled disks between machines 100s of times.

That being said, I want to move this 3TB disk to the win8.1 machine and I can not get it formatted. That's what I need to know

You'll need to partition/format as GPT, and unless your computer has UEFI bios, you can not boot to a 3Tb drive..

format it in the win7 machine to GPT you mean? then plug it into the win8 machine?


Yeah I won't be booting. This is just another drive to add to the Drive Pool

With a 3Tb drive, The bios is what's important here.. What motherboard is it plugging into?

You may need to use diskpart to unmount the gpt partition.

Ok so do I want this GPT or MBR?
I guess I'm confused as to what's going on here...

 

[Homerboy]

Ok... right now, in the win7 machine, I have a 3GB partition in GPT format.

That chipset is too old to recognize the full 3Tb of the drive. You can use it as a secondary drive, but you will need to use a GPT partition instead of MBR.

What machine/board is it going into?

I formatted GPT in the windows 7 machine.
plugged into Win8 machine
rebooted and all 3TB are there.
added to Storage Space and I'm set.


Thanks for the direction/hints. Reading back on my posts, sorry if I sounded short with my comments. I'm overtired and trying to juggle 3 things at once. Frustration got the best of me.

Thanks again!
