File properties not showing correct data

Hello.

I have a problem with folder properties bringing up incorrect data.  This is not an isolated incident and is occurring in several folders.  Here's the scenario:  I am copying a folder from drive D to drive E.  Both are external hard drives.  Each folder has several layers of subfolders.  After copying, I check the main folder properties to verify that all the files copied.  They do not match.  When I investigate further, I find that all files and subfolders are copied, but the folder properties are showing incorrect data for at least one, possibly both of the folders.  

See the screenshot below.  I've brought up the properties for the 110905_concept older.  For the same copied folder, on drive D it says 43 files, 51 folders; on drive E it says 4,028 files, 387 folders.  Not even close to a match.  

Inside that folder there are 3 subfolders: for brevity I'll call them 100, 200, and 300.  When I bring up the individual properties for each of these, they match between the two drives, showing 43 files and 48 folders for 100; 454 files and 113 folders for 200; 352 files and 31 folders for 300.  Hidden files/folders are turned on, and there aren't any here.  See below:

If you add up the properties from the individual subfolders, it comes to 849 files and 192 folders.  This does not match the data shown in either version of the parent folder properties, so I now have 3 different data readings.  Clearly at least 2 of them are incorrect; possibly all 3 of them are incorrect (it would take hours to go through and count them manually so I have not tried that).  This is happening with almost every folder that has large numbers of files and multiple layers of subfolders.  

What's going on here and how can I fix it?
