Recently i used my external hard drive on a friend's laptop to transfer some files, without opening my hard drive in his laptop. Unfortunately after that when i tried to connect to my laptop and open to view them, i realized that my folders and files were hidden while the files and folders that i transfered from a friend were visible. I checked the property of my drive and it shows that my documents are still there but are hidden. How could i go about retrieving them? I have tried doing unhiding files and folders from windows explorer and also using following steps to take ownership of my files and folders, yet they are still hidden.
