Setup : Proxmox - 8.3 on MiniPC Intel N100 with 16gb Ram and NVME 512gb disk.

What I want to do : Connect ugreen USB to sata adaptor with 4TB HDD (seagate skyhawk) - file format exFAT - disk will be swapped to Windows11 PC for "manual" backup. This disk will be mainly used for CasaOS (LVT) with Jellyfin and syncthing.

The problem : When I connect this disk to MiniPC, go to GUI of PROXMOX and go to STORAGE gives me Communication Failure (0).
Tried lsblk and this is output
Code:
root@DOM:~# lsblk

Of course I tried plugging it to Win11 device and works mighty fine.


EDIT :
Tried formatting sdb in proxmox - not possible. Deleted all partitions in windows, plugged back in - still Communication Failure (0).
Tried another 2Tb disk - same happens.

So it is quite posiible that the device is badly handled in proxmox or debian itself - it is ugreen 30353 usb 3.0 to sata/ide converter with 12v adaptor.
