This happens whenever I connect and mount a USB disk $ sudo mount /dev/sdi1 /sata Then when I am finished with it, I do $ sudo umount /sata and then $ sudo eject /dev/sdi At this point the system log shows the below burst of errors (the disk is still plugged in).
Checking the system log I see this for the first time with kernel 6.5.12-200.fc38.x86_64
What is the correct order of commands when removing a USB disk?
TIA

AFAIK eject unmounts the drive, so you're attempting to unmount it twice. For removable USB drives, unmount on its own is enough.
