Error mounting /dev/sdb1 at /media/wu/Local Disk: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,dmask=0077,fmask=0177" "/dev/sdb1" "/media/wu/Local Disk"' exited with non-zero exit status 12: Failed to read last sector (3907027119): 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?


Everytime I tried to connect my Harddrive to my PC, I get this.

I cannot find the solution.

Plz help ?
I am so new at using Ubuntu.

what will fdisk -l /dev/sdb say?

When I write this on terminal it say

wu@Wu:~$ fdisk -l /dev/sdb
/dev/sdb açılamıyor

this means it cannot open

yes, please execute it as root.

How can I do that ?

usually: sudo fdisk -l /dev/sdb

When I did that;
it gave me that answer;

wu@Wu:~$ sudo fdisk -l /dev/sdb

sudo fdisk -l /dev/sdb

Is this an external disk? Did you try it to use on windows?

It is a Western Digital 2 TB External Hard Drive. I used to use it on my Windows 7. About 3 weeks before I start using Ubuntu. When I plug it to my USB 2.0, I directly get that warning, I wrote at the beginning of that topic.

looks like an improperly formatted partition, I would run a chkdsk (or similar) on windows to check if that reports any error too.

WD drives are formatted in the factory as NTFS
BUT!!!!

they have a tool / utility / some what hidden partition with a few MICROSOFT.exe programs in it


so you really can NOT use the first partition
sdb WILL NOT WORK
sdb1 will not work( that is the Microsoft utilities partition
so
sdb2 will be the drive

also
that would be the WRONG command

the linux driver for Microsoft windows NTFS is called "ntfs-3g "

so

PS.
if you are NOT sharing it with a microsoft OS
then you really SHOULD reformat it to a linux format
like
ext4 and gpt table




However

if ntfs-3g and fuse are installed ( should be by default)

just plugging in the usb drive should Just mount

it should just work
