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:

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 /mediaTo find the correct /dev/sdb location for your external drive look at the result of sudo fdisk -l.
Step 1: Create a folder
sudo mkdir /media/Skliros_DiskosStep 2: Mount NTFS filesystem
sudo mount -t ntfs-3g /dev/sdb1 /media/Skliros_DiskosPlease 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 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, the external hard drive that I am attempting to mount is referred to as sdb1. Note that the external drive is not mounted (because the MOUNTPOINT entry is blank), and, importantly, if I unplug the external hard drive, then I will not see the entry sdb1 anymore.
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=137That 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 $USER /etc/passwd: are respectively the 3rd and the 4th field separated by: man mountfor all the mount options
Ubuntu 18.04.5,
To mount and/or unmount a disk from the shell prompt (Terminal)
in the same fashion as an external disk gets mounted "automagically".
(e.g. /media/$USER/Disk-Label/ )
Prerequisite: the disk is visible as "disk" and possibly also as "part" in the output of;$ lsblk
e.g.
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT ... sdb 8:16 0 2,7T 0 disk └─sdb1 8:17 0 2T 0 part ...
Then it will look like this:
$ udisksctl mount --block-device /dev/sdb1 ==== AUTHENTICATING FOR org.freedesktop.udisks2.filesystem-mount-other-seat === Authentication is required to mount WDC WD30EZRX-00DC0B0 (/dev/sdb1) Authenticating as: $USER,,, ($USER) Password: ********** ==== AUTHENTICATION COMPLETE === Mounted /dev/sdb1 at /media/$USER/USB-exfat. $ ls -l /media/$USER total nnn drwxrwxrwx 1 $USER $USER 131072 jan 1 1970 USB-exfat $ ls -lA /media/$USER/USB-exfat total 0 $ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT ... sdb 8:16 0 2,7T 0 disk └─sdb1 8:17 0 2T 0 part /media/$USER/USB-exfat $ udisksctl unmount --block-device /dev/sdb1 ... Unmounted /dev/sdb1. $
Where $USER will be the login name of the current user, assuming that user is present is among those specified by sudoers (e.g. admin[?] and sudo group members).
