macOSX cannot read part 2


Someway the system thinks that the disk .dmg is mounted. I can se it in diskutility, but never on the desktop. If I try to mount it one more time diskcopy gives me error 35 , disc is already mounted. can it be mounted somewhere else where I cant see it? or can I access it through the terminal? Is this a known problem or just me & my macOSX?
