 If you want to check the disk space for a particular partition, do not search through all of the partitions and try to figure out which partition is the correct one.

 Instead, specify a filename or directory name. _di_ will resolve any symbolic links and determine the actual partition where the file resides.  This works when your system administrator has moved a directory to a different partition and created a symlink to the new location.
