I am also experiencing this issue.

Per the tail of this forum thread:   http://ubuntuforums.org/showthread.php?p=8110630
I was able to stop the continuous disk access by restarting the udev service.

Here's "top" at first login after a reboot:

Here it is after "sudo restart udev":

A check with "ps" indicates that devkit-disks-da did NOT exit when udev
was restarted, but did cease consuming large amounts of CPU and spinning
the disk.  There may be intersecting bugs here.
