Cannot access second hard drive

Question

I am new to Ubuntu and I need a little help...

Recently, due to a power supply interruption, my Iomega NAS broke. I've read that I was able to rescue the files that were on it by installing Ubuntu on a computer and attaching the hard drive from the NAS to it.

So yesterday, I installed Ubuntu on an old computer, the installation was successful. I can see my drive by using 'disk utility', but I can't access the files that are on it...

I am using Ubuntu 11.10. Can someone help me out please?

EDIT: now using Ubuntu 14.04.1!

Result of lsblk

Solution

First of all check if the system can see your disk with the lsblk command. if it does you need to gather the volume name from the command in your case its sdb. And the partition you want is sdb2.

Then if the system does not see it, it means that you have to mount it.

Create a mounting point:

sudo mkdir /media/sdb2

Mount the drive:

sudo mount /dev/sdb2 /media/sdb2

Repeat for any other partitions you care to mount (examples: sdb1, sdb3)

To make these permanent edit your /etc/fstab file

Well ubuntu 11.10 is pretty old could you try and update it?

[ubuntu starter]

OK, I'am creating a bootable usb now with Ubuntu version 14.04.1

[ubuntu starter]

OK, the installation of Ubuntu v.14.04.1 has finished. But I still can't acces my files... Could you help me out?

[Alex]

can you run a lsblk and show the output you can also try sudo fdisk -l to check which drives your system can see

[Alex]

Edit your question and put your output in the question not in a comment since its hard to read and its not formated correctly.

[Alex]

so the one you are trying to acces is the 465.8G sdb?

[ubuntu starter]

yes! My nas was 500 GB

[Alex]

Basically the HDD is probably just not mounted so I believe if we assume the NAS to be some sort of *nix you should be able to mount the main partition using this: mount /dev/sdb2 /media/'Insert Media Name'

[ubuntu starter]

If I use mount /dev/sdb2 /media/' Insert Media Name', I get the message: "mount: only root can do that" Any suggestions?

[Alex]

sudo /dev/sdb2 /media/'Insert Media Name' and change insert media name by the name you want like sudo /dev/sdb2 /media/backup

[ubuntu starter]

Now I'am getting the message "command not found"...

[Alex]

oh I forgot mount derp derp here you go sudo mount /dev/sdb2 /media/backup

[ubuntu starter]

Now I'am getting "mount: mount point /media/backup does not exist"

[ubuntu starter]

I don't get any reaction on that comment.. After I've done it for the second time I get:" mkdir: cannot create directory 'media/backup' : File exists'

[Alex]

there isn't supposed to be a reaction mkdir makes a directory. And the second time it says that its created so now try to mount your drive on it.

[Alex]

can you run this sudo file -s /dev/sdb2

[ubuntu starter]

I'm getting "ERROR: cannot read '/dev/sdb2' (Input/Output error)"

[Alex]

Do you know the Filesystem used by that drive NFS, AFP, OES?

[ubuntu starter]

Message: Reading package lists ... Done Building dependency tree Reading state information... Done The following extra packages wil be installed (a couple of packages are coming now, do I have to write them down?) ... After this operation 1,299 kB of additional disk space wil be used. Do you want to continue? I did Yes! Err archive.ubuntu.com/ubuntu trust/ main libgssglue1 i386 0.4-2ubuntu1 Could not resolve 'archive.ubuntu.com' (Another couple of Err) E: unable to fetch some archives, maybe run apt-get update or try with --fix-missing? I really appreciate your answers. Thanks for all!

[Alex]

sudo apt-get update
