Try simply to get the output of mount command to a file for further inspection Code: mount > /home/user/MyDocs/mount.txt Read the file mount.txt or attach it in your next post for more support. If you try to unmount a partition, the command doesonly expect one argument like Code: sudo gainroot umount /dev/mmcblk0p1
mount > /home/user/MyDocs/mount.txt
sudo gainroot umount /dev/mmcblk0p1
