Hello everyone! I have a REALLY STUPID QUESTION... !!!GET READY!!! First will

be short story about me and my Linux Experience:
So, I tried Linux a few times in the past. My first distribution was Linux Mint Cinnamon. Than I moved to the Ununtu, because I heard it's mainstream distro in Linux community.
After I tried Ubuntu, decided for something more extra ordinary, far away from Windows style. First distribution was of course Elementary OS. After this one I tried Manjaro Plasma KDE (i hope it's correct name of the version), because I watched a stream/video of YouTube channel CHRIS TITUS TECH LINUX. I was totally happy and satisfied with OS, I had everything what I need. But after some time, one game came out and my friend suggested me to buy it. And of course I installed Windows and spent A LOT OF TIME on this game. It was worth it, I had so much fun. And now I am done with gaming, because I played/tried everything what I was interested in. Nothing left for me. Really. And now I remembered the main problem.
1. Why adding external hard drive is so *** hard? I can't make it auto mount at the start. With those all stuff like permissions, read only/write, point of mount, path and so on.

And yeah. Which one distro is most suitable for user, who wants just open and use it + almost 0 random errors/stupid problems with everyday stuff (most stable I guess).
Because I heard reputation of Ubuntu dropped because of something about privacy (correct if I am wrong).
PC:
AMD Ryzen 7 1700x
Radeon RX 570 8GB
16GB DDR4 2400 MHz
2x SSD's (both 128GB) and 1x 1TB HDD
Currently on WIN10 Pro.....

Thanks in advance and have a nice day!
