Need help mounting slave hard drive in Xubuntu

DeepBlue

My Windows XP machine packed up the last couple of days giving the following error message:

A disk read error occurred. Press Ctrl + Alt + Delete to restart

Googling tells me that there are various causes of this error but unless the hard drive is banjaxed I should be able to install it as a slave into another PC which I've done with my Xubuntu PC.

The second hard drive is recognised by the BIOS and fdisk -l reports the following:

me@me-desktop:~$ sudo fdisk -l

/dev/sdb1   *           6        9726    78083932+   7  HPFS/NTFS

Googling and some Ubuntu forum threads lead me to believe I should make some changes to /etc/fstab to recognise the second hard drive and this is where my linux knowledge falls short.
My current fstab looks like this:

# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    nodev,noexec,nosuid 0       0
# / was on /dev/sda1 during installation
UUID=84d3b7cc-8945-48e9-9b20-f854228ce952 /               ext4    errors=remount-ro 0       1
# swap was on /dev/sda5 during installation
UUID=8e833655-c890-4d67-91bd-71afd869f85e none            swap    sw              0       0
/dev/fd0        /media/floppy0  auto    rw,user,noauto,exec,utf8 0       0

I'd appreciate some help in making whatever changes I need to make so that the second drive is readable. I don't want to format it (yet) as there are some files on it that I wish to recover first.
Any assistance would be greatly appreciated.

If you just want to mount it temporally to grab files off it then you don't need to edit fstab at all.

Just open up a terminal and enter these commands.

Firstly you need to install the ntfs driver (I'm assuming its formatted with NTFS btw.

sudo apt-get install ntfs-3g

Next you need to make a mount point. Doesn't really matter where, so I'll just go with your home directory.

mkdir ~/mount

Finally you need to do the actual mounting

sudo mount -t ntfs /dev/sdb1 ~/mount

When you are done you can unmount the directory and delete the mount point

cd ~
sudo umount /dev/sdb1 
rmdir mount

If you want a more perminant mount then you do need to edit your fstab. Its best to use UUID's as much as possible so first you need to get the right one for your drive. Run

ls -l /dev/disk/by-uuid

And look for the one that points towards sdb1. Next add the following line to your fstab:

UUID=(put UUID here)	(full path to your mount point)	ntfs	auto,users,uid=1000,gid=100,dmask=027,fmask=137,utf8	0	0

You don't really need all those options if you don't wan them. Its a matter of personal preference as ntfs has a different security model than linux.

Hope this helped.

Thanks, that was a great help.

The mount command gives the following error:

me@me-desktop:~$ sudo mount -t ntfs /dev/sdb1 ~/mount
ntfs_mst_post_read_fixup: magic: 0x00000001 size: 1024 usa_ofs: 459 usa_count: 65535: Invalid argument
Record 0 has no FILE magic (0x1)
Failed to load $MFT: Input/output error
Failed to mount '/dev/sdb1': Input/output error
NTFS is either inconsistent, or there is a hardware fault, or it's a
SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows
then reboot into Windows twice. The usage of the /f parameter is very
important! If the device is a SoftRAID/FakeRAID then first activate
it and mount a different device under the /dev/mapper/ directory, (e.g.
/dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation
for more details.
me@me-desktop:~$

When the drive originally failed in the XP machine I tried booting it from the Windows XP CD but I just got a blank screen.
I then tried a KNOPPIX disk and got the following error when I tried to access the hard drive:

Could not mount device.
The reported error was:
$MFT has invalid magic.
Failed to load $MFT; Input/output error
Failed to startup volume: Input/output error
Failed to mount 'dev/hda1': Input/output error
NTFS is inconsistent. Run chkdsk/f on Windows then reboot it TWICE.
The usage of the /f parameter is very IMPORTANT.
No modification was made to NTFS by this software.

The KNOPPIX error message tallies with the Xubuntu error message and would lead me to believe that the hard drive itself is toast.
I wonder if there is anything else I can try?

Assuming you've unsuccessfully tried running chkdsk /f and rebooting Windows twice you can try force the drive to mount with

ntfs-3g /dev/sdb1 ~/mount -o force

^^ Tried that.
Unfortunately it gives the exact same error message as the normal mount command above.
