Unallocated

[KoreanWaffle]

I'm unable to format part of my HDD. Its ~750GB that im unable to allocate. I cant find a solution

gparted live -> format it to NTFS there

[BestPCBuilder2017]

I've never seen that before. Is it attached to another partition in some way? Would you be able to explain the setup?

Well its a 3TB drive that I had to breakup because it wasnt able to use all 3TB as one partition. I want it broken into two 1.5TB partitions, but im unable to.

Did you format is as Master Boot Record or GPT/GUID?

Right click on the "Disk 1" section (to the left of the partitions) and select properties. Go to the volumes tab and see if it uses MBR or GPT. If it's using MBR, you may need to convert it to GPT in order to use more than 2TB of the drive. Bear in mind that converting to GPT will erase the data (there are some ways to not lose data, but it's generally best practice to clear all partitions, then convert and rebuild from a backup if you have data you need to keep). 

 

EDIT: Easiest way to convert to GPT is to delete all partitions on the drive so it is all unallocated space. Right click on "Disk 1" again and select convert to GPT. You can also do it through diskpart command line if you wish:

 

Open command prompt and type in DISKPART and press Enter
Then type in list disk  (Note down the number of the disk that you want to convert to GPT)
Then type in select disk number of disk
Finally, type in convert gpt.

I'm not sure. How would I be able to find that out? I used the windows disk management to format it

Do a low-level format to get rid of ALL the partitions.  Then using something like the AOMEI Partition Manager to split it up.  After creating your partitions, then you can format each one however you want, NTFS, FAT32, etc...

Ah, yeah, Its MBR.

Edited my post explaining how to convert to GPT. Try that and see if you can use all 3TB

I'd recommend making it GPT/GUID. Back up your data on the drive before you do it though.

Alright, thank you, Im going to do a backup in a few days and I'll apply this. Thanks for the help everyone

Quick question, would the OS drive also have to be GPT/GUID to recognize/use it or would it be fine with MBR?

No problem. Make sure to let us know in this thread if it works (or if it doesn't and we can try to help).

It would be fine with MBR. MBR just has issues with drives over 2TB. So long as the drive in question isn't over 2TB, it doesn't matter if it's running MBR or GPT really (it's best to just use GPT on everything though if the hardware supports it. MBR is outdated and its only point is legacy support now)

 

EDIT: I used to have my OS drive using MBR and my 4TB HDD in GPT worked just fine.
