Edit: I was wrong; some motherboards can support GPT when running Windows 7. You can't boot from a GPT disk, though.
Again: I'll be darned, you can boot with a BIOS boot partition. Why do you want to use GPT - got drives larger than 2 TB?
Are you saying it doesn't matter about the motherboard as long as I use windows 7?
looking at building a raid5 array of 1tb drives.
windows 7 64 bit
asus m4a87td/usb3 motherboard
I'm not looking to boot from it but I want to have it really big without having to split it into multiple volumes, just keeps everything a lot tidier.
