    I have Ubuntu Linux 12.04 version the latest right now.I want to mount an external HDD NTFS 1TB.I have followed many guides but still no success.The error I'm getting is this:

    Failed to read last sector (1953523119): Invalid argument
HINTS: Either the volume is a RAID/LDM but it wasn't setup yet,
   or it was not setup correctly (e.g. by not using mdadm --build ...),
   or a wrong device is tried to be mounted,
   or the partition table is corrupt (partition is smaller than NTFS),
   or the NTFS boot sector is corrupt (NTFS size is not valid).
Failed to mount '/dev/sdb1': Invalid argument
The device '/dev/sdb1' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
Using Storage Device MAnager i get this error:Error mounting: mount exited with exit code 1: helper failed with:
mount: only root can mount /dev/sdb1 on /media/Skliros_Diskos {external disk name}

    When I use sudo fdisk -l, this is the output:

    what is the output of 'fdisk -l'? and which command are you using to mount the HDD?

    Try to see if there is an entry in the disk list with

    sudo fdisk -l

    Then try mounting it with

    sudo mount -t ntfs /dev/sdb1 /media

    To find the correct /dev/sdb location for your external drive look at the result of sudo fdisk -l.

    for partitioned drives, use `sudo parted -l` instead of `sudo fdisk -l`

    Step 1: Create a folder

    sudo mkdir /media/Skliros_Diskos

    Step 2: Mount NTFS filesystem

    sudo mount -t ntfs-3g /dev/sdb1 /media/Skliros_Diskos

    Please note the spaces. As per your comment on the question, you did not add spaces in the command.

    You should not mount it on the /media directory, since the system might use it thus might not allow you to umount the disk easily. Another reason is, when you plug-in another external drive, Ubuntu will automatically create a directory in the /media and mount the system on that directory, which could probably have some side effects, as the /media directory would be your external drive.

    Once mounted, you can access it normally through Nautilus (The default Ubuntu GUI file browser). It should be listed in the list on the left side, if it isn't, press Ctrl+L and type /media/Skliros_Diskos.

    Or you access it in the terminal with cd /media/Skliros_Diskos.

    I used the command of step 2 and i get the same error.I copy/pasted it to be sure.I didn't made it on mounting it so i can't follow the next steps

    @Slash Are you sure your NTFS volume isn't corrupted? `sudo ntfsck /dev/sdb1`, this command will scan an NTFS volume for errors, are there any?

    i get the the same error with before

    When i use this command "sudo ntfsck /dev/sdb1 " I get the same error with this command "sudo mount -t ntfs-3g /dev/sdb1 /media/Skliros_Diskos"

    I tried to mount the volume of skliros_diskos from disk utility i get another error which is this:Error mounting: mount exited with exit code 1: helper failed with: Unprivileged user can not mount NTFS block devices using the external FUSE library. Either mount the volume as root, or rebuild NTFS-3G with integrated FUSE support and make it setuid root. Please see more information at http://tuxera.com/community/ntfs-3g-faq/#unprivileged

    @Slash I understand your rush, I really do, but please you have to be patient a bit. Try running `sudo apt-get update` and `sudo apt-get install --reinstall ntfs-3g` and the try remounting the volume, after it's done reinstalling. If that also fails, try mounting with the following command: `sudo mount -t ntfs-3g -o umask=000,user /dev/sdb1 /media/Skliros_Diskos`

    i tried and done whatever you said .. still it isn't working

    In this case, I believe your NTFS might be damaged. Do you have access to a Windows installation, where you can try plug-in the NTFS drive on it? Whether it works or not, you should do a file system check on the drive.

    Tell me the correct way please on how to do that

    Dan

    Dan 8 years ago

    I do not have access to any Windows installation near me, and it's been a while since I accessed one. But I'll help you with what I can remember. After you plug it into a Windows machine, open the `My Computer` folder, locate your external drive and right click it. After that, click on `Properties`. There will be a `Check disk` button or something in that meaning in the properties page, click it and a small window will appear. Tick the `Automatically fix errors` checkbox and click OK. After error checking is done, try mounting it again on Ubuntu.

    I wish people would have read this guy's comments. His problem and solution are stated when he says "Unprivileged user can not mount NTFS block devices using the external FUSE library. Either mount the volume as root, or rebuild NTFS-3G with integrated FUSE support and make it setuid root. " Anyway the answers to this question were helpful to me solving my own problem.

    @Jistanidiot It would be great if you can input your own answer on how to do it!

    @Dan as I pointed out "Either mount the volume as root, or rebuild NTFS-3G with integrated FUSE support and make it setuid root."

    I find more cosy the use of lsblk instead of fdisk -l even because recently it is not always needed to specify the file system type a priory. Moreover I want to mimic the behaviour of the mounting through Device Notifier with the command line. Tested on Kubuntu 14.04 LTS.

    Step 1: Individuate from where

    To individuate where is I prefer to use lsblk (from util-linux package)

    lsblk

    That gives something like

     NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 931.5G  0 disk 
├─sda1   8:1    0 925.5G  0 part /
├─sda2   8:2    0     1K  0 part 
└─sda5   8:5    0     6G  0 part [SWAP]

sdb      8:16   0   1.8T  0 disk 
└─sdb1   8:17   0   1.8T  0 part

    In this case is sdb1, it is not mounted (no MOUNTPOINT) and if I unplug the external HD I will not see anymore this entry.

    Step 2: mount

    If I want to mount it in an existing directory /Full/path/ and my user id uid =1000 and my group id is gid=1000 I can use directly

    sudo mount  /dev/sdb1 /Full/path/ -o uid=1000,gid=1000,utf8,dmask=027,fmask=137

    That gives me the same mounting option that I have when I mount it graphically through the Device Notifier

    Notes:

    • You can see your uid:gid with grep $USER /etc/passwd : are respectively the 3rd and the 4th field separated by :
    • man mount for all the mount options
