Hello !
Here is the situation : I have two laptops. One is a Lenovo Legion Y540 running Cachyos and the other one is a Framework Laptop 13 (AMD series) running vanilla Arch.
I have an USB stick (Kingston DataTraveler 16gb) and I wanted to make it an Arch installation medium. While I can do whatever I want on my Framework Laptop of this stick (put a partition table with partitions, copy the Arch iso on it), I have troubles on the Legion. everytime I plug it it does not recognize the partition table and the partitions of it, and when I try to mount a partition, the menu of KDE showing removable disks keeps appearing and disappearing. I also have another usb key, which works fine on both laptops.
I don’t even know if it is related to Cachy, Linux or hardware, but I am ready to provide any information that you ask for.
