I'm new to Linux. When i firstly tried other distros my 2nd hard drive wasn't mounted on startup. I asked on Mint forum and managed to make it mount automatically through Gnome Disks. It moved to /mnt/Disk2, but was working. Now i was trying to do the same through the KDE partition manager when installed KDE Neon, but i couldn't make it mount to /mnt/Disk2, and when i'm trying to mount it to other places Steam can't see my disk there to make steamlibrary. It seems to mount at startup and requiring my password the second time, it's inconvenient too. Now i don't even know how to return it, help please.

Solved: mounted through Gnome Disks to /mnt/Disk2, but steam still couldn't see it. I uninstalled the Flatpak Steam and installed it from official site, now it works
