New HP server. 5TB disk size, but only showing around 2TB! Why?!

hi guys,

So I wiped a new server entirely (from the HP Smart Array, I deleted all logical drives and recreated them). Since I've done this, I went ahead and installed Windows on one of the partitions. It is a 5TB disk. However, in Windows, it only shows as 2TB disk and the rest is missing?! Surely there needs to be a way to release this 3TB?

I've taken a snapshot.

Any ideas what I can do here?

Cheers

It's because MBR only supports 2TB. Delete all partitions and convert the drive to GPT. You then should see all of the space.

So delete all partitions. Then convert this 5TB entirely into a GPT? Then install the OS?

Ah, I see. The OS needs to be on this drive, eh?

You need to install Windows by booting the media from UEFI instead of BIOS.

Or, create two logical disks, one that is around 100 - 200 GB and the other have it be the remaining space. You can then install to the smaller logical disk and MBR won't be a draw back for it. Then in Windows you can initialize the larger logical disk using GPT.
