Let's see exactly what you are doing in Manjaro to try to open the LUKS drive. As root in a terminal on Manjaro, please copy and paste into a reply email the output of lsblk -f command, before connecting the LUKS drive, and again after connecting it. ("lsblk" contains two lower-case letter L) The above command output will show the name of the drive, and it will look something like sdX. Please copy and paste into a reply email the output of the below commands with the drive connected. You will need to repace sdX with the name seen above for your drive. cryptsetup --version cryptsetup -v isLuks --type luks1 /dev/sdX cryptsetup -v isLuks --type luks2 /dev/sdX When copy and pasting, be sure to include the command that you entered, with its output immediately underneath, so that we can see the command that generated the output. In the same manner, please show us the command you are typing to try to open the drive in Manjaro, together with its exact output.
