My system isn't in UEFI. Never had a large enough HDD to need it. Now I do. I can see my 4TB is split into 2 volumes but I can only format 1 of them in windows. The other has all the options greyed out (using admin tools). What do I do to get that other volume to work as well.

[edit] NVM, I thought GPT only worked under windows with the OS partition being in GPT which needed UEFI boot. Just redid the 4TB in GPT and it worked lol. Durp.

ya but I thought I read somewhere that in order to use GPT, you had to boot from UEFI. Or is that only relevant when you want to use that large of a HDD as a boot drive?

TL;DR Since XP, 64-bit Windowses can use GPT drives as non-boot storage regardless of BIOS or UEFI motherboard
