All of a sudden I am unable to import photos from any of my external hard drives to Lightroom CC 2015. Also, the app is generally sluggish. In addition, the app hangs tonight, and I had to use Force Quit. No problems until this evening. Am using almost-new iMac w/retina display.
Please post the exact error message that you get while importing to your harddrive.
Normally this issue is related to Permissions to Read/Write from Harddrive
And you should have Read/Write Access for External drive.
