Recover Data From a dead hard drive using ddrescue
by Admin @ 9:07 am.
Like dd, dd_rescue does copy data from one file or block device to another.dd_rescue is a tool to help you to save data from crashed partition. It tries to read and if it fails, it will go on with the next sectors where tools like dd will fail. If the copying process is interrupted by the user it is possible to continue at any position later. It can copy backwards.
Imagine, one of your partitions is crashed, and as there are some hard errors, you donít want to write to this hard disk any more. Just getting all the data off it and retiring it seems to be suitable. However, you canít access the files, as the file system is damaged.
Now, you want to copy the whole partition into a file. You burn it on CD-Rom, just to never lose it again. You can setup a loop device, and repair (fsck) it and hopefully are able to mount it.
Copying this partition with normal Un*x tools like cat or d
[SOLVED] Can I use Linux to recover files from corrupted hard drive?
location: linuxquestions.com - date: January 25, 2010
So I have a simpledrive 1tb and it's not being recognized by neither PC or MAC.. both computers ask me to initialize/format it!!
On a different forum I was told that I could use Linux to retrieve the files.. I tried UBUNTU? but it didnt even show the drive when I plugged it it.
I would like to know if I using Linux will help me recover my files?
and if so where could I get the ISO?
hope you can help, thanks.
Newby that needs to recover data from failed NAS drive (xfs formatted)
location: linuxquestions.com - date: February 23, 2008
I have never knowingly used linux and am a bit lost so please forgive my lack of techinical expertise / lingo.
I have been operating a FNS-1000 NAS with a single hard drive installed on my home network - all PCs run Windows. Last week, I was suddenly unable to see the disk installed or access any of my files.
These are the actions I have taken so far:
- I attached it to a windows PC and the drive can be seen but obviously no files and I have declined requests to format it :-)
- I have installed the disk in question into a windows PC as a 2nd hard drive and booted up using both Ubanto and Knoppix. Both could see the drive but could not mount it (Can't read superblock error)
- I have used a System Rescue CD (http://www.sysresccd.org)and am just completely muddled as to how to use it - I found a graphical interface that had "GParted" and could see the disk and it's partitions with information about how much had been used on it but I really didn't know what to do
[SOLVED] Reading Data from Seagate hard drive extracted from Seagate Central
location: linuxquestions.com - date: August 29, 2014
As a way of introduction, I wouldn't call myself a linux newbie, rather a linux ignorant person unfortunately but I appreciate if you can help me regarding this critical issue to me.
I have purchased the Sagate Central NAS drive (3TB) a year ago and for no reason now there is no electric power at all and thus I cannot read anything on the drive at all. Since the data on the NAS drive is very valuable to me, I decided to disassemble the drive and connect it directly to my computer.
The problem is I can't seem to read anything on the drive on my Windows 7. I have researched the issue and it seems the problem is that the file system on the drive is ext4 (Not so sure about this since I know nothing about linux and the drive is not recognizable by Windows). I have tried several linux readers including (Paragon ExtFS, DiskInternals, and Ext2explore). The latter two seemed to be able to explore the drive, however, they see it as 4 partitions (a couple 1GB partitions and a cou
[HowTo] Recover Data From Seagate BlackArmor Drives
location: ubuntuforums.com - date: November 23, 2010
I ran into an issue where a Seagate Blackarmor 220 unit went bad (the device would not boot properly). So I needed to recover the data from the raw hard drives themselves (the backup appeared not to be working). I spent about an hour trying to figure out how to recover them as there was no information to be found via Google. So I'm posting it here...
To start, connect the SATA drive to the computer. I used a USB converter, but you can connect it directly.
Second, verify which drive it is:
It'll likely be the highest lettered drive (sdb for me). It should have 4 partitions (sdb1 -> sdb4). The data partition is the last (sdb4 for me)...
Now, the drive uses mdadm for raid, and ext3 for the filesystem. So first, let's setup mdadm for the device:
sudo mdadm --auto-detect
Now, let's find the mapper:
You should see a device similar to vg0-lv0 in the list. If so, mount it by specifying the file-system type:
How to recover data from external USB Drive
location: linuxquestions.com - date: March 29, 2008
My friend has a Western digital 160GB external USB drive. The drive suddenly stopped working. It gets detected in windows, but doesn't show up in "My Computer". When he checked the status of the drive in device manager it showed up as corrupted.
It doesn't get detected in Ubuntu 7.10 as well (He is using Dell 1520 laptop with Windows Vista and Ubuntu 7.10).
Now he wants to recover data from the drive before sending it for RMA. Any ideas about recovery tools in Linux using which he can get back his data. He has tried several tools in Windows without any success.
Recovering Data from a hard drive
location: ubuntuforums.com - date: March 14, 2013
First let me provide a bit of a back story. A few years ago I bought a D-Link DNS-323 NAS so that my wife and I could keep our photos and important digital media safe (ran it as RAID 1). The last few years it has been giving us problems. I always wanted to fool around with Ubuntu/Linux and finally found the time. I set up a basic server with some help, and it finally came time to transfer the files. Turns out the one disk is dead, can't get any info off of it.
The second one is working, but it will not let me access it. I tried to use the hard drive in the DNS-323 networked, but it won't let me access it (permission denied). Used the DNS-323 ftp server, and with that I was able to access it and see the files but I couldn't download anything. Unplugged the hard drive and plugged it into my Windows machine (used a program that will read ext2/ext3 formatted disks) and it would not let me in. Finally I plugged it into my Ubuntu machine and did a fdisk -l, and it told me the partition was

[SOLVED] How to recover corrupted data in external hard drive
location: ubuntuforums.com - date: July 17, 2008
I think the data were corrupted when I use VirtualBox. Anyway, I still can see all the folders in XP (my wife's laptop) even though I just can open only a few because most of them are corrupted, therefore prevent me to open. However in Hardy Heron, I do not see any folder (this USB external hard drive was successfully mounted) as if it was empty. I think Ubuntu refuse to show the folders (in the external HD) because it was corrupt. How to recover all my precious data (thousand of personal photos from 2 years ago till now, important documents etc). I already run dosfsck -a (the whole night) but it yield nothing. Hope something can be done because no one in their sane mind want to be parted with these kind of files (photo especially
Moving linux partition from original hard drive to another, howto???
location: linuxquestions.com - date: July 8, 2004
Ok, so I want to move my 25GB linux partition to a free 40GB hard drive I have. This will make my 80GB hard drive free for windows, this one drive for windows, and one drive for linux, in my computer. Basically, i just want to move my linux partition to another hard drive. Is there an easy way to do this, or does it get complicated? Thanks.
