Ubuntu :: Using TestDisk To Recover Lost Partitions?
Nov 16, 2010
I had 10.04 installed in parallel with a bad windows OS. Used the 10.04 to pull the documents, pics, etc off of windows. Worked great. Then when I tried to delete the windows partition it screwed grub up an instead of just re-installing grub. I re-installed ubuntu, what the heck it was gonna get wiped anyway. I didn't back up the pics and documents. I did however have them in all the ubuntu folders for my pics etc.
I feel like total crap, anyway, how good of a chance do I have at getting something back with testdisk? After doing a "deeper search" I come up with multiple partitions but it won't let me restore all of them. I really dont care if I can't boot to a single one, just as long as I can get the data back. (always can use a live CD).

My main partition having all my data like movies, music, files,etc has become inaccessible. Its file system was NTFS. Due to some recent resizing using GParted, the partition as well as my WIndows 7 OS has become unbootable due to some errors. The data partition's file system has become unknown. I don't care much about the OS but I would like to recover my drive. I am trying to achieve this using Testdisk and Photorec but haven't met with much success so far. The main problem is I can see my partition and all my files through Testdisk but I am not able to copy them to another drive. When I try to copy the option I get is of copying them to the DVD and not to any other partition.

I woke up this morning to a non-booting 9.10 computer. After my grub screen disappears, I get the familiar Ubuntu b/w logo in the center of my screen. My hard drive cranks for an abnormally long time and then I get the following error:
I booted into a live CD and opened up GPARTED and my sdb4 (my /home location) partition shows up. I do a check on it and it seems ok.
I opened the Palimpsest Disk Utility to see what it said and it shows sdb4 as Unknown or Unused. I can not mount this drive using GUI methods.
I did some research on the forums looking to recover lost partitions. here is the output from fsck
Code:
and the abbreviated output from fdisk -l
Code:
Disk identifier:
This seems ok too.
My next step was to try testdisk. When I ran it, I was able to navigate this partition and apparently see all my files. I then tried to mount the partition manually.
Code:
That also worked.
It seems to me that I practically have this thing where I need it without too many worries.
My question is: What is the next step to get this back booting again? I'm afraid of rewriting the partitions in testdisk until I get some feedback on whether this will really solve my problem. Maybe the partition isn't the problem? Is it something else and I've been going down the wrong path?

I am trying to recover data from my blackberry and a USB stick and after some research on the web I came through the Test Disk software which i just downloaded with Ubuntu Software Centre. I was looking to find information on how I could use this and recover files from my Blackberry and USB stick.

I have stupidly and inadvertently formatted my home partition on my other system while trying to 'downgrade' to Ubuntu 9.10. I have isolated the hard drive and am currently using Testdisk to discover the partitions on there. The scan hasn't yet finished however it appears there are two entries of each partition.
Here:
Linux 0 1 1 4012 254 57 64468776
Linux 0 1 1 4012 254 57 64468776
Linux 4013 0 1 14032 254 59 160971296
Linux 4013 0 1 14032 254 59 160971296
Linux 9079 0 1 14032 254 61 79586008 [home]
Linux 9079 0 1 14032 254 61 79586008 [home]
When attempting the downgrade, I was wanting to keep the home folder (and root and swap) all at the same size. I am pretty sure I fouled up by trying to revert the file system type to ext3 from ext4. Which partition out of the two 'home' ones, I should be attempting to keep? I cannot see a difference between them but this is how testdisk has reported the drive. Apart from the standard 'back up everything next time' and more fitting for me 'pack up your PC and never use it again!', does anyone have any specific advice on recovering my original home partition?

Because a customer of mine is inefficient in doing backups I have to do a recovery if possible. Drive had vista on it and was really bug infested to point of a reload. I reloaded vista from scratch and then my customer says "Oh, I guess I forgot to back those files up...".Is it possible to recover some files even though vista was reloaded? I suppose the basic answer is "As long as they havent been overwritten yet".
Im running testdisk and its made a ton of directories with files in them that I assume it has recovered. Im going to have to write a script I guess to grab the files as there are about 600 directories!I guess what Im asking is 1. What are my chances of success? 2. Has anyone ever recovered files from a vista re-install? 3. Is testdisk the best way of going about it (with photorec).

I tried to recover deleted data using testdisk tool and now my partition table have some errors. Even though i have 3 partitions and 1 unallocated disk fdisk -l shows only 1 partition
Code:

I was running Windows XP SP3 when one of my drives (or partitions) suddenly wasn't accessible. I booted into an old ubuntu Live CD I had (version 8.X) and tried mounting it. I could see the other partitions at this time. I rebooted the machine a couple of times (for normal reasons) and after a particular reboot none of my partitions were present! All seemed to have gone! I didn't do anything except mount the partition from Ubuntu Live CD. Made no write operations .
fdisk -l gives me this:
Code:
Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
[code]....
to list the files and I get:
Code:
Can't open filesystem. Filesystem seems damaged.
I originally had 6 partitions (including my primary). What do I make of the above screen and how do I proceed? Mot of testdisk documentation says "Choose the paritions to recover..." but I do not have a partition. What do I do to recover my data? I don't mind reformatting my entire HDD, but I need to get some jpegs and movie files off it first.

I resized my root partition yesterday to make it include the unused 28GB at the end of my drive, but something went wrong and now I can't mount it again.. I think this has to do with the computer coming with Vista preinstalled and the partitions not being aligned to cylinders. This is what the partition table looked like before the resize (according to fdisk):
Code:
Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xdec3533c

None of the last two partition schemes works, when I try to mount sda6 I get an error saying that the XFS superblock contains an invalid magic number. I've tried running xfs_repair on it, but even though it found a few secondary superblocks it couldn't verify them. I've tried running testdisk with the "Cylinder boundary" option set to "no", but it would not find my root partition... The log from the search is here I don't really care about the other partitions, all I need is my old root partition so that I can copy all the important stuff to another drive and then start from scratch with a new partition table (and remove the recovery partition aswell since I don't need it).

I need a way to recover my Windows partition that was completely repartitioned when I originally moved to Ubuntu.
When I first moved to Ubuntu 8.04, I somehow overwrote my Windows partition. It happened on a laptop and since then, I've purchased a new one so I can now go back and attempt to unzip the partition holding 10.04 and get to the files I had under Windows.

I'm using Xubuntu and have lost my bottom status bar so that if I minimize programs they vanish from the screen and I have no idea if they are running or not and cannot recover them, I cannot use web mail notifier either as I cannot get to the icon which is normally at the bottom of the screen. I suspect one of my kids have altered settings some where.

I was trying to resize to the left the sdb5 partition where ubuntu is/was installed and things got messy. I lost the partition it was unallocated. Next "cleverly" used livecd and reinstall ubuntu (thinking it was just like a repair the system thing) but instead ubuntu install from new...all my data is lost...gone with the wind. I try sadly enough testdisk but it says partition corrupted impossible to recover. Now the whole disk shows as unallocated in gparted.
I am running ubuntu from a second hard drive and strange enough my windows 7 partition with files is save and sound. I wonder if there is anything I can do to recover my files (guess the enitre partition now is lost). I try photorec and no files were able to recover then try scalpel and it says files were not find or couldn't read the partition. Of course "cleverly" I didn't had a recent back up of my files. Now I cant access the new ubuntu partition that still in sdb5 at boot takes me directly to windows 7.

The principal at my High School (currently my Bosses boss) brought a flash drive down today with the windows message "The drive is not currently formatted, would you like to format it now?" I grabbed by Debian laptop and went to work. So far, I have had no luck recovering the partition table or partition using testdisk or r-studio. I tried to dd a copy of the drive and examine it. The whole image appears to be goose eggs. I am not sure where to go from here. Naturally she did not back the drive up as my boss told her to and the documents on it are irreplaceable

I inadvertently started creating a boot disk over an entire 300GB external hard drive. Needless to say, I had all sorts of data saved on there. I stopped it early on in the process by turning off the drive, but I now I don't know how to salvage what's left.

I installed Ext2fsd from windows XP because I needed access to a text file on my ubuntu install. However, it didn't work because the drive is ext4 and all it listed was the root folders (/home, /var etc..) nothing any deeper.
I closed the app and continued working in windows.
Today I went to start my computer and it loaded the grub-rescue> prompt. I immediately tried to run "help" to find out what happened, however, grub reported the command as unknown.
I then ls and got a partial listing of the partitions.
Code:
(hd0) (hd0,5) (hd0,1) (fd0)
So what do I do? How do I recover my linux partition? If the partition is bad - then how is the bios able to find the grub-rescue> prompt?

I bought a new dell studio 1555 from best buy about a year and a half ago. Got the warranty because I have 4 kids and something is bound to be dropped, spilled or smashed at some point. True to my visions, something did get dropped smashed and spilled, and pennies got stuck in the dvd slot. So I took it in when the screen stopped coming on because of a loose connection in the hinge and they did apparently fix that problem, but also were benevolent enough to wipe out my entire hard drive, operating sytem and all, totally free of charge. I guess they figured since I like accidents so much, I would just LOVE having 18 months of data and programs disappear into thin air. I know all about how I should have backed it up, and I am not whining too much over this. I will roll with the punches. But there are just a FEW things on that hard drive I will really miss. Like a few crucial spreadsheets that I was not able to save to my external drive before the screen went south. Now that windows 7, I am not planning on missing at all. In fact I am loving running my new Ubuntu 11.04 from my usb and knowing that those idiots will not be able to screw this one up next time. But I would really like to be able to recover those files if I can. Is there any way to get those back? And I also cannot figure out how to find device manager. Do I have to install to hard drive to use that? I know these are all probably total newbie questions. But hey, i got here as soon as I could. Everybody has got to start somewhere.

Now am terribly frustrated because i reinstalled my linux installation(Ubuntu 8.04) after falling prey to an inode error. So i reinstalled stuff under my root partition under which i had some files which i obviously lost.I have tried recovering the files (mostly mp3 files) using photorec and the max file size i managed to recover was 4.0MB. the rest fall in the tune of 300kb.My question is, is there a way to make a full recovery of the above files seeing that they indeed can be recovered?

I was following a tutorial about 6 months ago that I think may have been for a different version of Fedora than I was running. Long story short I screwed up my installation and cannot get past this screen. The login screen has lost all of it's custom GUI theme and I can't log in. For one reason because after 6 months I can't remember my password (which is also strange because I only use the same few passwords for OS logins). I also get this error that pops up and then goes away on it's own.
Install Problem!
The configuration manager defaults for GNOME power manager have not been installed correctly. Please contact your computer administrator. I also get a caution sign icon like this one in the system tray on the login page. When I click on it it tells me that:
Starting Avahi deamon... [FAILED]
I'm not sure I want to spend the time fixing the install as I was planning on giving KDE a spin. I do, however, want to be able to recover some files on the partitions that Fedora was using. Can I just install Fedora KDE on a fresh hard drive and be able to see those partitions automatically and then transfer it to an external? Or will I have to find and mount all of those partitions manually? Also, will I even be able to gain access to those files considering I don't remember my password?

my mother wanted to update her iphone and during the process something happened and all of the phone has been wiped and we don't know what to do, regular recovery tools only work with regular storage media and the iphones file structure is too advanced to the point where you can only do this with a machow can i recover the data if there was no backup on the computer that it was using to upgrade

I have a dual boot Acer Aspire One, after reinstalling Windows back to "original factory", the way it was straight out of the box, it now will not boot up at all. It goes to the Windows start screen goes blank, and loops there infinitely. Is there a USB tool I can use to figure out what went wrong and recover either my Windows or Linux partition with out having to do a complete reinstall?

I am preparing for RHCE. While doing the lab I renamed /etc/grub/grub.conf as grub1.conf. Now (obviously) system boots on grub> prompt. Can I recover without using a bootable CD? Another problem that I encountered was, while doing lab for fdisk, I used command umount -al. Now, fdisk -l is not listing the partitions but giving a message:- /proc/partitions does not exist. If I reboot the system this is restored.

I have 3 drives in my computer. I installed Fedora 11 on my two biggest one, with the LVM treating them as one single drive. I attempted to install XP on my last drive. As I was installing, I selected my third drive (I'm 100% sure it is the correct drive as it is an 80gb whilst the others are 120 and 200 respectively) and told it to delete the partition on that drive and format. After I did that, it started to format, starting with my 120! I'm fairly sure that it was merely a quick format, as it only took 5-10 seconds for it to format, and that my data is still there. Is there any way to recover my "lost" data, or did I just really screw myself over?
