If you can't drag and drop or copy paste it's either a problem with the computer or disk. Have you tried doing this on another computer? On the other computer attempt to copy to a USB flash drive.
If the copy fails on another computer then you are looking at a problem with the disk. How old is this disk? You may be able to recover the files using something like Minitools Data Recovery or Easeus Data Recovery where 1GB of recovery is free to determine if the program will work.
A freeware version of Data Recovery would be PhotoRec but the files are recovered in real time and the names would be generic with the proper extension. You would need to open each file and rename accordingly. Also you would need to have enough free space on your hard drive.
Choose none for a partition table.
