sudo apt-get install sg3-utils (only needed the first time)
ls /dev (to check whether sr0 or sr1, usually it's sr0 unless you had already other USB drives connected)

In the cross-platform environment of our university, at least three different OS connect to the smb shared group directories. Apparently Macs are able to save files with characters that are not allowed on other platforms and which cannot be easily deleted. Recently we had several files which ended with a '.' (dot) or a ' ' (space), and we were not able to remove them via the GUI. In Windows 7, I managed via the command line with:
delete "file." or
delete "file "
If I am not mistaken, Windows is the only OS, that uses local time for the system clock (instead of UTC). This means that in multiple boot configurations, every restart of the system into Windows will screw up the system time. In order to reset it (in Ubuntu 16.04), use
sudo timedatectl set-timezone Etc/UTC
