Comment 4 for bug 297338

UID 500/1000 issue spun off as seperate bug

Sandisk HAL listing does not include the correct HAL properties, and thus fails the test in /usr/share/activities/Journal.activity/volumesmanager.py
--
        # Ignore volumes without a filesystem.
        if device.GetProperty('volume.fsusage') != 'filesystem':
            return False

Not sure whether this is a bug with sugar-journal-activity or with the HAL fdi's
