It is recognized by the system, but may have no partition table or partition. Check also the output of sudo fdisk -l — vanadium, Nov 03 '21 at 14:21
According to your dmesg output it would make sense to to see the output of sudo fdisk -l /dev/sda, also check if the device is shown with lsblk -f. — mook765, Nov 03 '21 at 14:49
out put of sudo fdisk -l /dev/sda is ```fdisk: cannot open /dev/sda: No medium found — WhySoSerious, Nov 03 '21 at 15:10
You can find some more ways to analyze the problem in this link and if you are lucky, find a solution. — sudodus, Nov 05 '21 at 17:18
