This shows the output from the dir command:

Z:\>dir
 Volume in drive Z is dept
 Volume Serial Number is 7DA6-7404

 Directory of Z:\

06/15/2013  02:24 AM    <DIR>          .
06/27/2013  01:48 AM    <DIR>          ..
01/17/2014  11:01 PM    <DIR>          SW
03/18/2014  09:42 PM    <DIR>          QA
               0 File(s)              0 bytes
               4 Dir(s)  1,009,809,938,155,520 bytes free

Note all those free bytes. Perhaps the problem is with more than 1PiB
of free space.
