I recently had to replace my vista Home Premium operating system. I have my photograph stored on two external hard drives. I am able to access the music and documents on the external hard drive, but not the photographs. When I try to open a folder I am given the message that I do not have "permission to access this folder". How can I be granted that permission to ALL the photo folders ( app 50) on that hard drive at the same time? Very aggravating situation !!!
