Try if this changing the permissions does anything useful. Try to unmount the MyDocs partition or just simply ignore the errors. This is for the common setup, where MyDocs is on the first partition and a FAT32 file system. Code: sudo gainroot umount /home/user/MyDocs chown -R -P user:users /home/user mount /dev/mmcblk0p1 /home/user/MyDocs
sudo gainroot umount /home/user/MyDocs chown -R -P user:users /home/user mount /dev/mmcblk0p1 /home/user/MyDocs
