Pls help.. cannot add files on disk

[Jhay Santos]

I was just transferring my file to my FreeNAS folder then suddenly, I cannot change the files anymore. When I create new folder, it shows a warning that says cannot create folder. access denied. When I delete files, it says that the disk is probably write protected.
What to do? I didn't change any setting in the web ui.
Thanks!
