Big thanks to peterleinchen but I am wondering if this is not an /etc/fstab problem(entries are exactly the same as my 'good' N900) but something different preventing user from writing to MyDOcs but sudo/root writes fine. What could keep chmod -R 777 from fixing the permissions issue and why wont remounting -o loop fix it?
I wonder if there is something wrong with settings for user?
Anyone?
