Recover Data on Seagate Central NAS Drive

The only app you would need is Unetbootin which you can download here.

If you're using Unetbootin you would be as well to select a Linux distro from the menu in Unetbootin, and download it that way, as not all Linux distros work with Unetbootin. Other than that though it shouldn't matter which one you use.

Then it would just be a matter of booting up your computer with the USB, find the name of the offending partition in Linux using fdisk, create your mount point in /mnt, then try to mount the offending partition there.

With a bit of luck, if it doesn't work, a more verbose error message will be displayed in the terminal than the one you got with Diskinternals.

For the benefit of anyone reading this who is less familiar with Linux, this is how to mount a partition in /mnt.

First of all find the name of the partition using fdisk:
 

al@my_desktop_pc:~$ sudo fdisk -l
[sudo] password for al:

In this example I'll mount the partition called /dev/sda8

Create a mount point in /mnt. You can name the mount point whatever you like, but I'll call it sda8 for the sake of continuity
 

sudo mkdir /mnt/sda8

Now mount the partition in the mount point:
 

sudo mount -t auto /dev/sda8 /mnt/sda8

Job done. You should now be able to access the partition either in the terminal or with a GUI file manager.

 

EDIT: the above commands apply to distros that have sudo installed, and where your user name is in the sudoers file. If you are using a distro that does not have sudo installed or your username is not in the sudoers file, then omit "sudo" from the above commands and instead either use the root terminal, if your Linux distro has one, or else use super user by running the following command before you begin:

su

 

EDIT2: If you are using Puppy, you won't need either sudo or su, as you run as root anyway.

Ok I am sure this is just the start of a long list of hoops to jump through.

 

I created a distro of xubuntu using Unetbootin, then i rebooted and the USB drive said "boot error"

 

I do not really want to redo this process in case I missed something

 

Standing by....

What version of Windows are you using?

 

If it has secure boot, you might have to switch that off in the BIOS if you haven't already done so for the computer to be able to boot from USB. I don't have secure boot so unfortunately I don't know anything about it, but there are others here that do so hopefully one of them will chime in before long if that is the issue.

 

I take it that you didn't get as far as the Unetbootin boot menu, which should look something like this?

 

 

http://www.howtogeek.com/howto/linux/create-a-bootable-ubuntu-usb-flash-drive-the-easy-way/

Yes I did not get to the boot menu at all

 

What i did was download the unetbootin software, Im on windows 7, then i chose ubuntu as the distro, it downloaded it then told me to reboot, i can see the grub and boot files on the USB

 

my system does not have secure boot that I am aware of

 

Did i miss a step?

Did you select USB in the boot priority menu in the BIOS?

Well in my BIOS its "removable device" my sandisk Cruzer, but yes I did select it, and it comes up with a black screen that says "boot error"

Did you select USB in the boot priority menu in the BIOS?

Should i try another distro, maybe that one was bad?

Was the USB formatted with fat32 (or fat) file system?

If so, do you have access to another computer that you could try and boot with it to ascertain if the problem is with the USB or the computer?

Is there any more than a single partition on the USB?

I'm not sure what the problem might be, so all I can think of is to eliminate possibilities.

Hi jaysodyssey!

 

I suggest you to follow my steps from the last year.

 

1 - Boot an Ubuntu's distro - is the most user friendly distro and  the more complete.

 

2 - Use the apt-get to install de R-Linux. Ubuntu allows you to install softwares temporarily, even with booting distros.

 

3 - Run the R-Linux to rebuild your file partition.

 

Some observations:

 

1 - I recommend you to install the linux, because this process will take more than a day of work, maybe tow days to rebuild your 3Tb. I've the ubuntu installed and I took 5 hours to rebuild 300Gb.

 

2 - If you couldn't install the linux, use an USB 3 device to achieve more speed.

 

3 - Yes, the partition has to be rebuild. The linux will see your mounting point but won't be able to mount the files. So, you have to use th R-Linux to rebuild all your data bit by bit.

 

Good luck

Ibiki Did you get all your data back doing this method? I have a spare computer I could use I guess, but I would need to throw a hard drive in it,

Yes! I got everything as they were.

 

When I tried to run the R-Linux version for Windows, it worked to, but all my data structure became corrupted, ie the windows version cannot rebuild the folder structure. Only the linux version will restore all as you leave.

Ibiki and others

I am starting the process now - seagate just shipped the new drive

 

I have a dedicated computer to do this on, I will attempt to load UBUNTU on a usb drive (that already failed once on THIS computer, might work on the other one)

 

And then Ill follow the steps

 

I have the computer loaded with the 4tb and a 160gb master drive

I am writing from inside Xubuntu now, installing R-linux as we speak, I will update soon!

Ok I have R-linux installed but clicking on execute does nothing!

 

Ill wait for a reply
