Half of my 5TB hard drive partitioned to cd rom?

[ahappydude]

I just did a new build and install and my 5tb hard drive partitioned 3tb to a cd rom. I am unable to format this partition and i cant merge to the c: drive.

I dont know how this happened and am willing to reformat everything if necessary.

That can't be right, I think you find D drive is your CD drive with the Asrock Support CD in it. I can see where the rest of 5tb is, its behind the current C drive.

What are the specs of this PC? Is it a custom or Brand name? If brand name, what make/model? if custom, what motherboard?

What I suspect is the case is your PC is set up as legacy boot format and as such, its set the drive up as MBR. MBR can only access max of 2.2tb on a drive, so its ignored the other 2609.53gb on the hdd and left it unallocated.

What you need to have or do, is a UEFI bios set up to use UEFI boot method and then it will use GPT format on the drive and allow you access to all 5gb

Welcome to Tom's Hardware, @ahappydude!

I'd second everything that @Colif mentioned. Your 5 TB HDD is not partitioned with half in CD-ROM but rather you don't have a UEFI-based motherboard or you simply used the MBR partition table to initialize the HDD in order to boot from legacy BIOS. Sharing you PC specs will definitely help us assist you.
Besides the helpful article regarding the partition tables that has already been shared with you, I'd also suggest you check this tutorial from the community regarding Installing Windows OS onto larger HDDs.

Hope it helps you. Keep us posted with your system details & let us know if you have additional questions.

Thanks for your help, I was able to change partitions and make it a GPT drive. This was my first complete computer build and I am happy to see everything is up and running!!!
