Hi,
I am relatively new to Proxmox so please forgive me if my descriptions are a bit vague.
I am trying to recover the content of a volume I created using Proxmox.
Chain of events:
1. I installed proxmox on HDD A.
2. Added another HDD B. I believe that I provisioned it is a volume for a windows 10 VM. The drive was then formatted in the W10 VM.
3. Disconnected HDD B for ~6 months.
4. HDD A replaced by HDD C. New installation of Proxmox on this disk.
5. Reconnected HDD B.
After connecting the drive, I can see that the data is there but I don't know how to access it... Would really appreciate any advice of how to do this.

The files I am trying to retrieve is on /dev/sdc3, and the size of ~7tb is correct.
