Lost data after power cut

[Obednal1]

Background:
One 4TB HDD partitioned for home network
Setup multiple VM's and Containers
After a power cut, all my vm's and containers came back online, bar one - Plex Media Server
Proxmox gave me the following error when trying to start the server

run_buffer: 321 Script exited with status 9
lxc_init: 847 Failed to run lxc.hook.pre-start for container "107"
__lxc_start: 2008 Failed to initialize container "107"
TASK ERROR: startup for container '107' failed

After reading other forums I found that removing the mounted storage file vm-107-disk-1.raw on /mnt/pve/NetworkStorage connected via dev/sdb3 from the Plex server would enable me to start it up again

This worked and I could login to plex, although of course as I detached the storage file I was unable to access any of my media

When trying to add the storage file back it gave me the same error when trying to start the server

Really hoping I haven't lost 850GB worth of data

Here's an old thread from when I was setting it up incase it provides any further info
https://forum.proxmox.com/threads/data-container-from-ext-hdd-plex-proxmox.122723/

Massively appreciate any and all support on fixing this

Update:

I was able to mount the storage file by adjusting the 107.conf to
mp0: NetworkStorage:107/vm-107-disk-1.raw,mp=/mnt/media/,size=2000G

unfortunately, it's still not showing the files where I would expect to find them in /mnt/media/

Ran this on the Plex server, I guess this suggests the entire data is lost/missing, Maybe something I did after the power cut

There wasn't a solution to this because I now know what I was storing data on before was a virtual drive space, instead of the physical drive being bind-mounted which is what I have now
