External HDD needs format

Hello to all. Havent been here for a long time between the windows system has improved a lot over the past tear.
To my latest problem i was given an external hdd but it has two sections as per image how do i get this to a full working drive please.
Many thanks

Hi there @menu

from Windows command mode

1) Diskpart
2) list Disk
3) select disk <disk4> I think it would be in your case
4) clean
5) convert gpt (optional step but I prefer gpt HDD's these days even just for data disks)
6) create partition primary
7) format fs=ntfs quick
8) assign
9) exit

now you should have HDD ready for use and assigned a disk letter.

you don't need to create an efi partition for this disk either.

Unknown Not Initialized Disk unknown not initialized issue can be caused by various reasons like virus infection, file system damage, bad sectors, MBR corruption, partition loss, etc. It is the easiest way to fix disk unknown not initialized issue by clicking Initialize Disk option.

Thanks once again

Sorry to get back to you.
Forgot about this one. Can I change this into one to get rid of the small section.

Thanks.

Please open the Command Prompt by typing cmd.exe into Start Menu, right-click on Cmd.exe, and open it as an administrator.

Following commands will delete all partitions and data on disk 4.

Code:

Diskpart

List disk

Select Disk 4

Clean

Create partition primary

FORMAT FS=NTFS QUICK 

Assign

Exit

Thanks.

You are very welcome!
