Umbrel storage not showing properly?

So i installed Umbrel on SD card , and after that I connected 1TB SATA HDD, when i go to umbrel setting it shows only external storage data not sd card data and its usage same with other “File browser” or any other file management app (Samba) its only showing external storage data.

How can i access all my umbrel data?

I know only that you have to mount properly your drive to your system.
Your goal is probably to extend “SD card size” by this extenrnal disk.

I have similar goal extending internal SSD by external one. There are guidelines but none is working for me with UmbrelOS 1.2.2 on x86 system.

I am not giving up yet. It is Linux, it will work.

I had similar solution for other PC. I have solved that by making my /home directory pointing to extenral drive.
