Unable to access photos on external drive. Permissions error
So I have thousands of photos, saved in folders (i.e. not iPhoto or Aperture Library or anything like that, just as individual files). When I try to open them from the external drive, I get an alert that the photo can not be opened because I do not have the correct permissions to access the file.
On the drive, I have read/write for all users and admin but aside from that, the "ignore permissions" checkbox is checked too.
So I first tried unchecking that so maybe it'll look to the invididual user priveledges instead but that didn't work. I then copy/paste one of the photos to my desktop, and I get the same error.
Is there a way to reset all permissions on the drive for all the files ? I'm not sure how I can access the photos now :
OS is 10.8.5 (was doing this on 10.8.4 too)
MacBook Pro with Retina display, OS X Mountain Lion (10.8.2)
