Hello. I use openSUSE Leap 15.3. Trouble is, when I attach USB sticks from 16-128 GB there are no problems. They are mounted and read immediately upon being attached. When I attach large external USB disks, there is a different story. The disks most often do not show up. Sometimes they do, but most times I must read the disks (formatted with EXT4, FAT32 and EXFAT) on a Mac laptop in order to access them. Which, admittedly, makes me ashamed. The question is why this happens. To elucidate the problem, I have typed fdisk -l and dmesg, and the results are in the links below. I shall be extremely thankful if you can have a look at these outputs and see if you can spot the source of my problem. If these files do not provide a clue, please tell me what commands I should try next. In both cases, an external disk was attached. However, the system failed to see it. The fdisk -l output: http://www.coldsiberia.net/technics/fdisk_l_21042022.txt The dmesg output: http://www.coldsiberia.net/technics/dmesg_21042022.txt Sincerely, Per Inge Oestmoen, Norway
