USB disk not recognise like storage

I have a minipc of HPE with Zima OS inside. I want to use an external USB 3.0 2Tb disk like storage for some container. (The System HD is a NVME of 256Gb) I connected it and the system recognize that there is a new device but when i click on it I cannot use it like storage. The system recognize it and say that there is 2Tb space on the system but i cannot use this space in any container and if I try with File App i cannot go inside the USB disk.
I tried to mount it manually from the terminal but same thing. What I’m doing wrong? I attach some screen from dashboard and terminal.

Hello, and welcome to the forum.

A couple questions, What does it show inside the Storage tab of settings? What format is the drive in? Does it need to be formatted first?

Hello thanks for the reply,
inside the storage tab I can see an attach USB disk, but if I click on the folder the system open file but immediately appears a popup with the error “storage not mounted”.


I formatted the disk with the terminal in ext4 and GPT table.

I already tried to clean all partition and reformatted it but nothing change. I already tried to restart the system

Any news?is not possible to use a USB disk on Zima OS?

There is something off with your sector size. Ext4 defaults to 4096 byte sectors for systems 512 MiB and larger . What helped here was to Ext4 format and partition the disk using mini tool partition wizard under Windows keeping parameters default

I had the same issue and formatted the USB HDD with ext4 under DSM. After connecting it to ZimaOS, I was able to mount and access it directly. This should also be added to the developers’ to-do list.
