udiscs --monitor gives the following

..etc
where sdd is the user data partition, sr0 is a non-writeable partition holding the security software.
Workaround: "sudo stop udev" lowers the CPU load. Seems to work fine after that, but surely not an elegant move .
Additional info:
udisks version 1.0.2-4ubuntu1
udev version 167-0ubuntu3
Fix reported using "sudo hal-disable-polling --device /dev/sr0" ubuntuforums. org/archive/ index.php/ t-1478339. html
