when unmounting a usb disk, by command umount or by GUI (right click on icon then select “safe remove”), the usb disk just get unmount, but it is still ON.
but the command udisk --detach /dev/sd* turns [b:2ra465iu]OFF[/b:2ra465iu] the usb disk. so it’s safer to remove the disk from the socket.
is it possible to use udisk command instead of umount in GUI applications? or merge umount and udisk.
