Question: Hello again!

It’s all about that WD 1TB external HDD that I ignorantly used as a flash USB to download Linux, turning it into a 2.80MB mass storage device.
I’ve been able to recover my most important data with DMDE thanks to Fzabkar’s help here, but I found in Disk Management that there is an unallocated partition of about 930GB in the disk.
I tried both formatting as NTFS and as simple device but nothing happened. I even tried Easeus Partition master. No result.
It remains unallocated.
Can anyone help me out with this?

Thanks!
V.O.
