Permission error - Failed to enumerate objects in the container. Access is denied.

Here is how I solved my issue -
1. On the root folder, right click, select properties, select security tab.
2. Click Advanced
3. The window that pops up should show the current owner. Click "Change." The "Select User or Group" pop up box appears.
4. In the text box, type in your current user name (you should be an admin), and hit the "Check Names" button. Your name will be replaced with the "official" system name (i.e.,preceded by computer name and back slash).
5. Click OK
6. The box disappears, sending you back to the Advanced Security Settings window.
7. A new tick box appears below owner, with the text "Replace owner on subcontainers and objects" Select this tick box.
8. I also selected the tick box "Replace all child object permission entries with inheritable permission entries from this object", but I think I had to run this twice - once with this box ticked and once without.
9. Make sure that "everyone" appears on the Permission entries window, if not, click add. The same box that appears in step 4 shows up again. Type everyone, click "Check Names" and then "OK"
9. Hit apply

I also see that the folder ownership can be changed to "everyone" - I haven't tried changing all my folder owners to this, but doing so might eliminate this issue altogether if the drive is moved to a different computer.

Hope this helps someone, this problem and lack of documentation was quite aggravating.
