I have a WD 3TB external drive I used with Windows 7 just fine, and now want to use it on my laptop as a FTP accessible drive.

For some reason though I cannot mount it (I get an error when attaching it already).

The error I get is

Failed to mount '/dev/sdb1': Input/output error 
NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID/FakeRAID hardware.
 In the first case run chkdsk /f on Windows then reboot into Windows twice. etc...

after I used first

sudo ntfsfix -b -d /dev/sdb1

which resulted in no bad clusters, and processed successfully.

Then I followed the steps described in http://ubuntuforums.org/archive/index.php/t-1307581.html but still was not able to get the harddrive to work on Ubuntu. I did try the chkdsk /f, and that said there were around 300 MB of system files on the drive, but I cannot find them on Windows, and Ubuntu won't mount, so I cannot check if there is something hidden on there.

A

fdisk -l

resulted in:

Disk /dev/sdb: 3000.6 GB, 3000590401536 bytes
255 heads, 63 sectors/track, 45600 cylinders, total 732566016 sectors
Units = sectors of 1 * 4096 = 4096 bytes
Sector size (logical/physical): 4096 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disk identifier: 0x2052474d

This doesn't look like a partition table
Probably you selected the wrong device.

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1   ?     6579571  1924427647  3376425012   70  DiskSecure Multi-Boot
/dev/sdb2   ?  1953251627  3771827541  2979336364   43  Unknown
/dev/sdb3   ?   225735265   225735274          40   72  Unknown
/dev/sdb4      2642411520  2642463409      207560    0  Empty

Partition table entries are not in disk order

What am I doing wrong?
