Fedora :: Testdisk Recover Data
Jan 6, 2011
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:
vishnu@vishnu-laptop:~$ sudo fdisk -l
[sudo] password for vishnu:

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 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?

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).

I have a laptop with Fedora 12 on it and I accidentally did an dd if=/dev/zero of=/dev/sda (since then I learned to think before I type)
anyway, I stopped it in time (I hope), it only zeroed first 60 MB. So, it killed partition table and boot partition. What I need is home partition, and it should be untouched. home is on a LVM device (fedora default install settings), and I tried testdisk (supposedly handles LVM) but it found only one partition (I guess it's a LVM physical device, as there should be 3 partitions, /, /home and swap) and said it's not recoverable.
Is there a way to get access to files on that partition (partition itself, including file table should be untouched). Partition contains various data (video, audio, and text) I need back (and it's my data, not backed up, and not something I can redownload). Is there any software that can help me with this, and if not, is it theoretically doable (I believe it should be, as the partition itself is not damaged, so it should be possible to read file names and link them with data on disk, am I right)? what is a good way to image the disk, so I can reinstall the laptop while trying to rescue data from image?

Using F12 with a LVM Volume, Single disk with OS on and boot partition. The OS HDD is getting i/o errors, but will still boot to the login screen. I've removed the HDD and connected it to a Fedora Live OS on my laptop, connected the HDD and it registers as :
[root@localhost]# fdisk -l /dev/sdd
Disk /dev/sdd: 250.1 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x000e0069
Device Boot Start End Blocks Id System
/dev/sdd1 * 1 26 204800 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sdd2 26 30401 243991201 8e Linux LVM
And it tried to mount /dev/sdd2 to view and see if I can recover some files.
[root@localhost]# mount /dev/sdd2 /mnt -t ext4[root@localhost james]# mount /dev/sdd2 /mnt -t ext4
mount: wrong fs type, bad option, bad superblock on /dev/sdd2,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
Any way to mount the partition to allow me to try and get some data back, or if trying to do a full backup of the drive you can get it to ignore i/o errors.

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?

I was testing a bug in F12+Acer Aspire One and its 'suspend' feature (you can probably find the thread) and I ended with my SDHC card messed up. I formatted it as ext2 (or ext3, don't remember exactly) and apparently its superblock got corrupted. For one thing there is a single file I want to recover from the card (I don't mind formatting it afterwards). I am no expert using e2fsck or fsck, that's why I am asking here. In addition I used the "dd" command to create a backup of the drive in a file (so I can start tinkering with it). What is the best course of action to recover my files? Either from the card or from the image?

My sister-in-law (SIL) has a Western Digital ShareSpace 4TB network access storage that was setup in a RAID 5 configuration (four 1TB hard drives). To make a long story short, a blinking red light on the device and a call to Tier 2 technical support, one of the guys mentioned using Fedora as a way to retrieve the data from the hard drives (seems like the hard drives are good but maybe the actual NAS device crapped out).
I will not have access to the hard drives till this weekend and of course Tier 2 technical support is closed on the weekends. I have almost no Linux knowledge but can follow instructions pretty darn well. I am looking to install Fedora 14 Desktop Edition 64 bit on my desktop sometime tonight or tomorrow. Once I have Fedora installed, how would I mount the hard drives and have Fedora read the RAID 5 array?

I've been using Ubuntu 10.10 on my EEE-PC for most of my thesis research, but I left it running a python script overnight and now I can't get it to login. I was running low on disk-space, and I think the problem is that the script generated a lot of text files and used up all of the available hard drive space.
Now, whenever I try to boot the machine, it reaches the user-select/login screen, but logging in just causes it to go black for a second before returning to the login screen. I have Ubuntu 11.04 on a USB, and Ubuntu Rescue Remix on another, and both allow me to boot up my machine, but I can't see my hard-drive - neither in /mnt/ nor in /media/ - in order to copy my thesis files or to delete some excess text files to free up some hard-drive space.

I have a DVD-R labeled 16x that has been written by me in several sessions (but perhaps only one), always with an iso9660 fs, using a DVD writer whose data are these:
Vendor_info : 'LITE-ON '
Identifikation : 'DVDRW LH-20A1H '
Revision : 'LL0D'
Device seems to be: Generic mmc2 DVD-R/DVD-RW/DVD-RAM.
kernel 2.6.21.5, GNU (Slackware 12.0).
In spite of the last line, the drive is DVD+R compliant too. This is the only DVD drive I have and it seems unable to read that medium. Other discs, it reads them well. Before kissing the disc good bye, I would like to try all possible procedures at my disposal. The disc, by visual inspection, seems to be in a pristine condition. When I insert it, the drive remains with the led turned on for about one minute. I tried 'cdrecord -setdropts driveropts=singlesession dev=x,x,x' to switch the drive to single session mode but with no results. I have many tools in the cdrtools package:
cdrtools:
FILE LIST:
./
usr/
usr/bin/
usr/bin/skel
usr/bin/mkzftree
usr/bin/devdump
usr/bin/scgcheck
usr/bin/mkisofs
usr/bin/btcflash
usr/bin/isovfy
usr/bin/readcd
usr/bin/isodebug
usr/bin/cdda2wav
usr/bin/cdrecord
usr/bin/isodump
usr/bin/isoinfo
I also have dvd+rw-tools.

I'm browsing on my phone which is not letting me scroll to the end of this text box so I will say thank you in advance for any replies now.After my computer was switched off abruptly after a power outage I have many errors upon booting. My hard drive setup consists of a RAID0 array of two 500GB sata disks. The partition table (from my head!) goes like this:50GB NTFS Windows XP /c/50GB ext4 Ubuntu 9.10 /4GB swapThe rest is a large NTFS partition all the way up to the end of the array at 987GB. Mounted at /media/share/I am thinking I will have to start again (I won't lose much, I have recent backups), but what is the best way of restoring the system as much as I can? Currently my computer has been booted into Ubuntu for over an hour, and after pressing ctrl+alt+shift+F2 I can see that it is finding errors still, now at sector 6008. Should I let this run its course or REISUB it and boot onto a live CD. I think the main problem is with an NTFS partition

Well, my laptop slid off my couch and crashed down onto hardwood floor. The hard drive is shot. I was using grub and had both ubuntu 10.10 and windows 7 on it. Can't load either OS.
What options do I have for trying to recover data off the ubuntu partition? I tried loading livecd...for some reason, it won't work. Does livecd require a working harddisk?

My friend has a DELL DIMENSION 9150 computer with 2 harddisk (250 GB each) in RAID 0 (fake raid) with Windows XP installed. There are a lot of documents and pictures installed - and no backup ever done! I have found some pages regarding recovery data from RAID 0 () but My friend have bought 2 new harddisks(WESTERN DIGITAL 2500AAJS) which is almost the same as the ones inside.
My plan:
1. copy each harddisk
2. replace original HDDs with my copies
3. try to recover
4. change RAID 0 to normal HDD in BIOS
5. reinstall Windows XP
I have some LINUX distros (DSL, SystemRescCD, UltimateBootCD on Live-CD and UBUNTU installed on one other computer) which I can use. I read about "dmraid" and then try to mounting the RAID in a UBUNTU live-CD version...

I wanted to get some data off a second disk, let me tell you what I did. (that didn't work). The data I am looking for is under /etc/ on the second disk. I looked in /dev for /dev/hda or hdb but there was nothing.
I found:
/dev/sda
/dev/sda1
/dev/sda2
/dev/sdb
/dev/sdb1
/dev/sdb2
So I guessed /dev/sdb /dev/sdb1 /dev/sdb2 was the second disk. So I did:
mkdir /tmp/olddisksdb
mkdir /tmp/olddisksdb1
mkdir /tmp/olddisksdb2
Then I did
mount /dev/sdb /tmp/olddisksdb and got mount: you must specify the filesystem type
mount /dev/sdb1 /tmp/olddisksdb1 and got no feedback (good?)
mount /dev/sdb2 /tmp/olddisksdb2 and got mount: you must specify the filesystem type
If I do:
ls /tmp/olddisksdb - I get nothing.
ls /tmp/olddisksdb2 - I get nothing
ls /tmp/olddisksdb1 - I get:
config-2.6.18-128.el5 symvers-2.6.18-128.el5.gz
config-2.6.18-164.9.1.el5 symvers-2.6.18-164.9.1.el5.gz

During a new installation of openSuse 11.2, because of a mistake, I lost access to previous partitions.
I was advised to use testdisk/testimage, but of course it didn't work, because my lost data had beeen encrypted.
How can I make linux ask me the previous root password?
I think any program that doesn't ask the previous password, isn't able to recover data. Is it true?

I bought an IcyBox NAS a little while back, and it recently died on me. I have physical access to the disks inside (1.5TB RAID 1 array), and the box was running a version of Linux. I now have the difficulty of retrieving the data from the disks. As best I can tell, the NAS uses software RAID. All I have available are 2 Windows machines, one of which has sufficient free space to hold the data from the NAS. I've booted one of the Windows machines into Linux using a Ubuntu CD, and Ubuntu can see the array drive(s), but cannot mount them.
What would be the quickest and easiest way to retrieve the data from the disks? What data can I collect from Ubuntu (10.10) that will help me pin down why it can't mount the array volume?

I have a full Ubuntu 9.10x64 install on an external hard drive and I was recently asked by a friend who has a laptop running 32 bit vista if I might be able to help him in recovering anything from pictures to Quick Books files. He believes the hard drive is corrupted. His laptop is an HP with less than 2 gigs of ram, and he is not sure about the motherboard/chipset. It may or may not support x64. He went out and bought an iMac the other day so he wouldn't need to deal with not having a working computer.
Now I have 2 questions. The first being, I am wondering if my x64 install will still be able to run if I tried booting to it from his computer in the event that the chipset that does not support 64 bit architecture, or do I need to revert to a 32 bit install? My instinct/what I perceive to be the obvious answer, is that yes, my x64 install should/will be able to boot via the bios. My second question is: how do I go about loading Ubuntu once the external is plugged into the iMac?

It seems my 320gb HDD has bitten the dust. The timing couldn't be more ironic as I have spent a couple of days tidying the files on it to burn them to disk.
This is an ntfs drive that had indicated 4 bad sectors but up until today (backup day) was fine. I am unable to mount it and in fact it is causing some sort of conflict with the OS drive and wont let the system boot up successfully.
I am going to try using a windows based PC tomorrow to see if I can rescue the data.
Are there any 'other' tricks to try and mount it with ubuntu that I may not have tried so far? I have tried-
mkdir /media/disk
fdisk -l to establish it's name which was /dev/sdb1 when it was all working but it isn't reachable and doesn't show in the places menu or in any of the menus when using a live CD to get round the HDD clash.
sudo mount -a used in desperation after the mkdir but nothing.
I rejigged the cabling inside the PC to make the HDD a secondary master as it was a slave on the primary IDE to start with in the hope that the system would boot up normally but to no avail.

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.
