I have a Samsung 5TB D3 external HDD. Something got screwed and it ended up as a RAW disk. I've managed to get it back to showing in W10 Disk Management as
Disk 2
Basic
4657.53 GB
Online
PARTITION 1 ?
N:
2048.00 BG NTFS
Healthy (Prmary Partition)
PARTITION 2 ?
2609.53 GB
Unallocated

I can create / delete files on the N: drive.
Can anyone tell me how I can merge this unallocated space into the N: drive? Windows 10 Disk Management won't let me do anything with it.

Thank you.
