3tb not recognized

[dznutz]

hi i recently purchased a 3tb drive to put in my rig. however, i cannot use all 3tb. i can use 2.2tb but the rest is un-usable. right clicking on that un-usable portion in disk management didn't give me the option to use it. my bios sees it as a 3tb drive so at least i know the mobo can see it.

am i correct to assume that 32bit windows 7 cannot use more than 2.2tb per drive?



hmm.... it turns out that gigabyte offers the 3tb unlock but it only supports certain chipsets: http://gigabytedaily.blogspot.com/2011/03/gigabyte-announces-3tb-unlock-utility.html

Issue of old BIOS. You need a board with UEFI to see the full amount on a single partition. You can split it into 2x 1.5TB partitions and it'll work.

thanks.

it turns out choosing "convert to gpt disk" will combine them together

Yes, gpt will fix your problem.

Btw, multiple partitions with the mbr-scheme will not fix it.
