I am not marking this resolved yet because "Local Hard Drive" is functioning as autodetect.
Then you have two bugs open for the same issue (see bug 17619) and one should be marked as a duplicate of the other.
The issue described in the bug description here has been fixed. If it does not fix the underlying problem, then it's not a problem with winecfg (indicated by the "programs" component selection) but probably in mountmgr.
