That's usually the last line of the output, the information before that has the more interesting details of what it found wrong.

that's all it said in the drop down window that appeared when it stopped repairing. the main window says:

checking file system
checking journaled HFS Plus volume
checking extents overflow file
checking catalog file
the volume Macintosh HD could not be verified completely
Volume repair complete
updating boot support partitions for the volume as required
