I thought i decrypted my hdd files before i removed the hdds from the system. I attempted to copy over the data to a new hd by using the old hdds as an external drive but it looks like the files were still encrypted. I have the old hdd and I never formatted it. is their anyway i recover the encryption key and recover my files? I also had to export the key to another user profile in the past so that other users can edit and view the files. I can't seem to find those either.
