I am working on a Mac and have a new Nikon D7100. I am fairly new to Lightroom and am using Lightroom 5. I am having problems importing photos from the camera to an external hard drive. I am able to import directly to my internal hard drive but when I try to import to the external one I receive an error stating, "The following files were not imported because they could not be read. (44)" and then a list of all the images I am trying to import. I have checked my external drive and there does not seem to be any issues with it. Any experience you can offer would be greatly appreciated.
This means you do not have WRITE permission to the folder on the external HD. Change your permissions.
Thanks DJ! I didn't know this could be an issue but I see now my external drive is read only on my Mac.
