The NTFS permission differences report has no Data in it, saying “Differences are not available as parent permissions are not collected”
Assuming the collected share permissions are for the C: Drive, discoveries like this could be inefficient, especially if you are including other shares on the C: drive, as the NTFS discovery will retrieve the same information once for the share and then again for the C: drive.

When reports are generated, they are large and filled with the same data for C: drive and any shares on C: drive.
If you would like to know what is on the C: drive and who has permission, you should instead create a discovery for the box and not select shares and hidden shares but specifically add the C: drive (C$) to the Include.
