Mount Points and OpManager

Mount Points and OpManager

I have been looking around in attempt to find the answer I am looking for but there always seems to be something missing in the posts that are preventing me from getting to my answer.
 
OpManager is currently running Windows 2008 with build 8723.
 
I have another server that is running Windows 2008 with parts of Exchange 2010.  This particular server has a number of mount points, one of which filled up over the weekend and causes some issues with one of the DBs stored on there.  I need to be able to monitor those mount points but can't seem to figure out how.  I tried a few things like partition tracking but it never has anything beyond the C and D drive.  Other suggestions are getting to be 2 years older.
 
Please, any suggestions would be of great help.
