I have a Buffalo LinkStation Pro Duo (LS-WVL) which was running two identical 4TB WD disks in a non-raid config, I will call them Disk 1 and Disk 2. I tried to install debian on it (Disk 1) but due to some reason, it couldnt boot so I decided to revert it back to stock. I deleted boot partition on Disk 1 to deliberately put it into Emergency mode and rebooted NAS with only one disk (Disk 1) which it has formatted. I know, I should have re-read the instructions more carefully
Anwyay I can see my files using UFS Explorer but I would rather prefer to have the partitions back if possible. I tried to revert partitions on Disk 1 using testdik but I am sure I have messed up again, as I will present below. Also, it is still booting in emergency mode.
Before the mess up, both disks had, apart from the system folders/ partitions, only one data partitions/ folder (with my data) in each "share" or disk. It was /Media/Movies/Movie1, Movie2, ... on Disk 1 and /Media2/TV/TVShow1, TVShow2, .... on Disk 2. There might be autogenerated hidden system folders and a rubbish bin in each too but I dont remember exactly.
When I run testdisk on the good disk (Disk 2), I get:

On Disk 1, I took a screeshot of the partition scheme when I was trying to install debian on it but I dont know how to upload the photo here.
Now, when I run testdisk on the messed up disk (Disk 1), it shows only one partition. When I search for partitions, it shows:

My questions are:
1. Which partition or patitions should I try to restore/ recover?
2. Is it possible to restore more than one partition (i.e., in the original manner), so that the NAS doesnt start formatting and reinstalling the firmware again on next boot up?
3. Less preferable but is it atleast possible to get the data partition back so that I can copy that folder and subfolders (/Media/Movies/.....) to another disk?
I have ordered another 12TB HDD in case I have to manually copy all data to another disk. I have access to both windows and linux machines.
Any help is much appreciated.
Thanks.
