I have this mounted iso drive which is empty and i cant remove it. When i try to eject it it says "error occured while ejecting...", when i tried to unmount it in powerISO it just deletes whatever is inside and doesnt actually delete drive itself. I tried removing it with cmd command but it says something like "This device is not ready". Disk manager doesnt see it at all so i cant remove it from there either. It is really annoying.... Hope someone helps!!! Thanks in advance.
