Lr won't import. Problem started in 5.6 but upgrade to 5.7 with hopes but problem remains. Problems started after COPY of RAW images to primary hard drive after accidentally import to secondary drive and duplicate to same drive.I tryed 2 SD cards. The card reader is well connected and the PC can see the images on the card reader.
So what happens when you try? If there is an error message, please quote the complete error message, word-for-word, verbatim, leaving nothing out (or show us a screen capture).
