I have done as directed and created the filesystem on the partition and listed it in fstab with defaults options. I mounted the partiton at the correct mount point. I see the file system correctly but it will not let me write to the file system. when i open the folder it shows a "lost + found" folder with an x in a red box above and to the right of the folder and an amber padlock below and to the right of the folder. when i try to create a file or copy a file , it says Error - you do not have permissions to write to the destination.
What am I missing?
