I am having a few issues with my external hard drive and being able to access the files on there. A wee while ago somehow I accidentally removed all the permissions from the external and I was unable to access any of the files. For the life of me I have no idea how to re-enable those permissions. Is someone able to please give me a walk through on how to do it?
Oh I forgot to add some of the folders have a little padlock in the folder icon, what does that mean?
