[Bug 1349533] Re: unable to mount large ntfs usb drive

[Johan Van Caelenberg]

"fdisk -l /dev/sdb" didn't work.

"I ran chkdsk /f in Windows and rebooted twice: still no result."
The disk labeled DATA_4 has only one partition and Gparted says it is 'unused'. So I ran chkdsk /f on that drive in Windows, got no errors, and rebooted twice. In PartedMagic the same Gparted description ('unused') but the partition is mounted nonetheless and I can read from it and write to it.

"It is probably the "fast shutdown" feature of windows 8."
Will forget about that.

"sudo ntfsinfo -fm /dev/sdb4" fails.

"sudo dd if=/dev/sdb4 of=bootsector count=1"
Results in this:
dd: error reading ‘/dev/sdb4’: Input/output error
0+0 records read
0+0 records written
0 bytes (0 B) copied, 0,00107704 s, 0,0 kB/s

The file 'bootsector' is empty (0 B)

"sudo parted /dev/sdb"
Results in:
GNU Parted 2.3
Apparaat /dev/sdb wordt gebruikt. (Device /dev/sdb is in use.)
Used the command 'toon' ('show') to view the partition tabel, but got the following error:
/dev/sdb: onbekend schijflabel (unknown disk label)

That's about it; it seems I'm stuck with an 'unused' partion that can
(PartedMagic) or cannot (Ubuntu) be mounted.

I appreciate your help very much, thank you.
Nevertheless I think I'm going to copy my hard drive's files to another disk in Windows or in PartedMagic, repartition my drive and format it ext4.
Doing that it will mount in Ubuntu, no doubt. Unfortunately it will be empty then.

Title:
  unable to mount large ntfs usb drive

Status in NTFS-3G:
  New
Status in “ntfs-3g” package in Ubuntu:
  Invalid

Bug description:
  Ubuntu release: 14.04 LTS
  Package version: ntfs-3g 1:2013.1.13AR.1-2ubuntu2
  I expected my 2Tb external hard drive to mount just like my other two 1Tb external drives, but it didn't.
  Instead, the drive icon appeared in the task bar, from which I could only select 'Open', not 'Unmount'. Trying to open it, nothing happened at all.
  Merged lshal.txt, devices.txt, dmesg.txt and udev.log into the attached file. The device that won't mount is /dev/sdb4, labeled DATA_4
  ck-list-sessions : doesn't seem to produce any output
  id haldaemon results in: id: haldaemon: unknown user
  uname -a results in: 3.13.0-32-generic #57-Ubuntu SMP Tue Jul 15 03:51:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
  Tried to get 'hal debug output' but the hal process wasn't found.
  fdisk -l results in the following error:

  Error mounting /dev/sdb4 at /media/jote/DATA_4: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,dmask=0077,fmask=0177" "/dev/sdb4" "/media/jote/DATA_4"' exited with non-zero exit status 13: Error reading bootsector: Input/output error
  Failed to mount '/dev/sdb4': 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. The usage of the /f parameter is very
  important! If the device is a SoftRAID/FakeRAID then first activate
  it and mount a different device under the /dev/mapper/ directory, (e.g.
  /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation
  for more details. 

  I tried "ntfs-3g" instead of "ntfs": same error.
  I ran chkdsk /f in Windows and rebooted twice: still no result.
