Lost all permissions to my NTFS partition

  • 772

I have lost "Write" permission for myself, and all other permissions for 'Others' and 'Group' on my important NTFS Partition(Contains all my Data). Any amount of Chmod(ing) or using the GUI to set it right isn't working.

I get this error when doing it the GUI way.(No other details of why it couldn't set permissions is mentioned).

    I got my answer on ubuntuforums.org

    I was using the ntfs driver and not the ntfs-3g driver. I just needed to install the ntfs-3g driver and everything worked properly.

  2. I believe your NTFS partition is mounted as read-only. This is the default behaviour when your NTFS partition is auto-mounted.
    To solve this issue first identify the device file for your NTFS partition. It will be in /dev directory so the complete file name would be something like /dev/sdaX. You can find this using Disk Utility. After this create a directory in your home directory and unmount your NTFS partition using the following command:

    sudo umount /dev/sdaX

    now remount it using the following command to have write access to it:

    sudo mount -t ntfs -o rw,auto,user /dev/sdaX /home/tintin/DIRECTORY_NAME

  3. I usually mount my ntfs partitions with the options:

    defaults,rw,user,uid=myusername,gid=mygroupname

    Of course this is assuming a single-user system. ^^

  4. Following the basic advice above I created 

    sudo mount -t ntfs -o rw,auto,user /dev/sda6 /Information

    so I can mount as wanted. I like it this way because many of the files there are very important to me, so not having automatic access is just another layer of protection.
