I did the same but the first time I clicked on the drive, it prompts for password, I've entered the username/password then it showed me the folders on the drive. As soon as I tried to open the folder, it again prompt for the username/password but this time when I tried the same username/password, I get access denied. I can't even access the sub-directories like you said. Mine is also formatted it as NTFS.I already had the sub-directories created. It was a drive I moved from my PC. Maybe you can unmount it and connect to a PC. Mine was NTFS format.
