Ubuntu :: Drive Formatted - Mount Partition For Disk Data Recovery

Nov 1, 2010

I accidentally formatted a 2TB drive of mine (big oops), but have recovered 2 of the 3 partitions using testdisk. My third partition is a LUKS encrypted partition. Testdisk managed to recover a piece of it, but it won't mount as most of it is unallocated. The partition originally occupied all space from sector 2,930,272,065 to the end of the disk -- sector 3,907,024,064. That is about 473 GBs. Currently, the partition only uses space from sector 2,930,272,065 to 2,930,288,129, about 7.84 MB.

The rest of the space is unallocated. Now what I need to do, is to expand the partition so that it occupies all the space that it used to. How would I do this? I cannot resize the partition, cause it would try to recreate the filesystem AFAIK and I don't want that, as it will fry my data. My data is not terribly important, but I would rather have it then not. I attached a screenie of kpartitionmanager. The partition in question is /dev/sdb2.

Ubuntu Installation :: Accidentally Formatted /home Partition - Recovery?

Feb 11, 2011

I was installing 10.10 x64 today. I wanted to manually partition the disks, since I have a /home partition from a 9.10 installation which I want to keep.Unfortunately, I selected to convert the ext3 /home partition to ext4 and didn't realise it was formatting the partition until it had just begun. In desperation, I pulled the power plug, but now I can't access the partition (using the LiveCD) - comes with an input/output error.What are some strategies to recover the data on the partly formatted partition? I don't think much, if any, was actually formatted.

General :: USB NTFS Disk Suddenly Won't Mount - Partition Gone / Repair It And MBR Without Losing Data?

Sep 12, 2009

Just ran into an uncomfortable problem. I usually never save any documents on my machine, and keep all my stuff on an external USB hard disk. (an 80GB TrekStor DS microdisk q.u)
Well yesterday this disk just would not mount.
Read through related posts but nothing seemed to work. Even tried it on a Windows machine.

Tried TestDisk utility. Found nothing wrong with the drive, but still could not repair the MBR.log code...

Palimpsest Utility recognized the drive, but just will not let me do anything with it except format it.

How can i repair the partitions and MBR without losing all my data?

Ubuntu :: Recovering Data From A Formatted Partition?

Dec 19, 2010

I just installed kubuntu 10.10, replacing an older installation. I have three hard drives one of which had all of the data I wanted to save, about 500gb. I repartitioned and formatted the other two drives and made sure that the data drive would be mounted but not formatted. When I booted into my new installation, the data drive was blank. I'm not sure if it's relevant, but I had just upgraded the file system from ext2 to ext4 before starting the installation.

I've been trying to recover my lost partition with testdisk. The website has instructions for recovering a formatted partition. It looks like it's working until the instructions tell me to choose Boot and RebuildBS, which I don't see as options. Can anyone give me any advice on how to recover? How did this even happen? Has anyone had a similar issue with installation?

Fedora Hardware :: Trying To Mount Drive - Create An Ext4 Partition To Move The Data

Jun 12, 2010

I just installed F13 x86_64 on a system that used to be running Windows 7.

The boot drive is a SATA drive attached to the motherboard which is working fine.

However, my data drive is an NTFS partition filling a 3.6TB SATA raid.

It's GPT--Gparted sees 3 unknown partitions, and gdisk shows:

Code:

How do I mount this in Fedora 13? I had intended to shrink the NTFS partition so that I can create an ext4 partition to move the data to. Will this be possible?

I've got a LOT of valuable data on this drive, and nothing else big enough to store it.

Fedora :: Recover Data On LVM Formatted Drive?

Aug 19, 2010

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?

Ubuntu :: Data Recovery On My Broken Disk

Mar 22, 2010

A while ago my harddrive kinda failed. I didnt notice untill I got "Grub error 17" one time when I was trying to boot my computer. The problem is not really that I couldnt log on to my computer, but rather that I have alot of important information on the computer I would hate to lose. At the time I used Ubuntu 8.04 and had reiserfs filesystem on the computer. I bought a new computer and decided to wait untill I could rescue the data before doing to much dmg to it. But I dont really remember if I tried something to fix it before I realised that it was the harddrive and bad sectors that made me get gruberror 17. Hopefully I didnt do anything.

Anyway. Now today I had some extra time, so I decided to dive in. I booted from a linux mint disk and used ddrescue to transfer all the rawdata over the network to an image file laying on an ext4 drive. Once there I used reiserfsck to try and repair the filesystem. After that i mounted the image file and tried to access the files. Thats where the probelms started. I could see the whole treestructure of the harddrive and everything seemed ok, but when i tried to open the files, none of the pictures, documents and so on could be opend, and when I tried to open stuff like MP3 files they played quite strange. Videofiles was really messy, kept changing resolution and was almost always just gray and green squares on the screen. I decided to use ddrescue and move the files from the image file and on to a clean disk. So when I was done I could mount the filesystem on the new disk, but with the same resault, so I did reiserfsck again, and when that didnt help I did a buildtree also. Still with the same resault. So I decided to investigate the data abit. Opening files at random trying to understand what had hapend. And I saw that some MP3 files (the easiest to open) was some kind of mixing between several difrent mp3 files. Some files wasnt even in the same folder, so it was probably just that the file pointer was pointing at the wrong data on the disk. I dont know how that works really, so I dont know how to go on.

So now to the question. How do I get the data back? Have I done something wrong, can I redo somethig? I still have the broken disk and can take data from it once again, but I want to wait to do that untill I really know what to do. I also still have the image file, and the disk with the copied data. I have a ubuntu 9.10 system at my disposal atm.

Fedora :: Wrong Drive Formatted - Recover Lost Data?

Oct 30, 2009

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?

Fedora :: Hard Disk Data Recovery Of Ext2 And Ext3

Jul 1, 2010

I am student of MCS and working on final project. I am the user of windows xp. I am new in Linux. I am working on a project that titles "Hard disk data Recovery of ext2 and ext3 in linux". In windows, including dos.h and bios.h header files in program of c language I can send interrupt to bios and access most of the devices like parallel port, hard disks etc. But problem is that there is no bios.h and dos.h files in gcc. Now how can I access my hard drive using c program. How can I call int13h interrupt in linux or there is any other function in the linux to access the hard disk. In fact I want to access sectors of my hard disk using c language program. How can I do it?

General :: Data Recovery For Overwritten Partition

Jun 27, 2010

While attempting to install FC12, Anaconda took it upon itself to overwrite the partition on my backup disk. Now I need to figure out if there's a way to get at least some of my data back. If there's a better place for this question, please let me know and I will happily move it. Using Linux since 1993, other Unixoid systems since 1986. I bought this machine back in 2004 or so. It was a pretty decent machine back then, but it's showing its age now: 370Mb of RAM, 2 hard disks with 80Gb and 120Gb (I don't think the other specs are relevant, but just let me know if I'm wrong). In a fit of insanity, I decided to install Gentoo on it. Don't get me wrong: I love certain things about Gentoo. But the constant fiddling that's required, while it can be fun at first, gets old kinda quick.

So various and sundry things have been going wrong with it here and there (CD-ROM, sound card, etc ad infinitum), and, finally, it wouldn't even load X any more (almost certainly some final Gentoo update which broke something) and I said "screw it, I'll just put Fedora on it." This is what I use at work, and plus I have a good friend who has far more patience with admin stuff than I do and Fedora is what he knows. So, last night, I pick up an FC12 CD that I have lying around and decide to finally just reinstall the whole thing. I went so far as to buy myself a Passport USB drive, 319Gb, and have been backing up up all my stuff very regularly to that drive. I go through one final cycle of backing up and verifying before I start the reinstall.

So my drive is solid, and contains everything I could possibly need (and probably quite a bit of stuff I don't). After booting into FC12, I used Palimpsest to explore the partitions on the existing hard disks. Not sure which was which, I mounted the Passport, where I have cleverly saved a copy of my fstab. Using this, I can see which of my partitions were /boot, /, /home, etc. Most of my personal data has been put into separate partitions so that I could reinstall without blowing away the data. I hope that I can do that there, but, if I can't, no matter: I have a backup. I find some bits of empty space and delete a few of the partitions and recreate them, consolidating the empty space. Still confident in my backup, of course.

So I run Anaconda. Nothing happens. Eventually, I figure out that it won't run the graphical interface because I don't have enough memory. I can use the text version, no biggie. It gets to the part about the disks. I tell it which hard disk to install itself onto. For some reason I think it's going to pop up and ask me about the existing partitions and whether I want to keep them or rewrite them (maybe that's a previous version of Anaconda? or a different installer altogether, who can remember). It does not. It babbles something at me about LVM (which I've personally never really used before), and then promptly locks up. Obviously standard Fedora on a low-RAM machine like this is doomed to failure.

I poke around on the Internet, and I eventually stumble on the Fedora "spins" and select FC13/LXDE. Hopefully this will have better luck. Reboot with the new CD, take a look at my hard disks. It has completely overwritten the old partitions, replacing them with LVM partitions. But not a big deal: I have a backup. Take a look at the Passport. Its ext2 filesys has also been replaced with an LVM partition. Proceed to beat head against wall. So, obviously what happened is, since I (foolishly) had the backup drive mounted at the time I ran Anaconda, it assumed I wanted it to take over that drive as well, and just formatted everything it could lay hands on as LVM. It certainly never asked me my opinion on the matter.

But, fine, I shouldn't have had it mounted. The question is, what do I do now? My first, panicked instinct, was to just set the partition type back to 83 (I believe LVM is 8E), which I did (using cfdisk). That might have made it worse; I dunno. But I'm pretty sure I haven't written anything else to the disk since then. I've tried testdisk (nothing useful; although it can seemingly find the underlying deleted partition, it won't actually do anything with it), and a bevvy of Windows Linux recovery programs (Stellar Phoenix, DiskInternals, Raise, and R-Linux), all of which were completely useless except for R-Linux, which scanned the disk for eight hours and was still going when I had to interrupt it (I may come back to that one, but so far it doesn't look too promising).

My primary problem is that I can't make an image of the disk because this little Passport is the biggest hard drive in the house. I would certainly feel better if I could image everything off it and then play with the image. But, of course, it doesn't matter that very little of that 319Gb was actually being used: I still need 319Gb worth of space to make an image. I ordered another (larger) Passport, which should be here Wed. Once I have that I believe I can do something like so:
Code:
dd ifs=/dev/sdX ofs=/mnt/bigpassport/smallpassport.img bs=512
Right? Then I can muck about with that image in some amount of safety.

Of course, I also have the original hard drives, which are not so large. testdisk can identify the original partitions on those too, but, again, won't actually do anything with them. If I could find something that would image just the partitions I care about, I could probably save those as well, but I don't have any other external hard drives with 120Gb of space free. Can I somehow take the info that testdisk is giving me about those original partitions and use dd to get only that part of the image? Are there other recovery tools I haven't considered? I have a Windows (Win7) laptop, a Linux laptop (FC10, I think), although its power cord is flaky so it's not too reliable, a smaller Mac, a really old Windows box (XP on it, I think), and this formerly-Linux box, which I can only boot off CD's at this point. There's nothing on this disk worth the 500 bux that professional data recovery would charge me, but it's worth a day or two of my life to try to get at least some of it back.

Ubuntu :: Hard Drive Recovery - Destroying All My Data ?

May 22, 2010

I'm running 10.04 LTS (64 bit) During a recent attempt at dual booting Windows 7, the Windows installer made a boot partition on the wrong drive, formatting the drive, and therefore destroying all my data.

The original partition was NTFS, and the new (unwanted partition) is NTFS.

Is there something in Linux I can do to recover the data that was there, or am I going to have to install Windows on yet another drive and use some Windows tools?

The data on this drive is extraordinarily important, containing ten years of digital photos, my source codes, and musical compositions (protools sessions etc).

Ubuntu :: Data Recovery From Windows NTFS Drive?

May 5, 2010

The other day one of my hard drives on my windows system decided to stop working. Not entirely sure what happened, but it seemed that it just erased its partition header, although I wasn't able to recover it.

Anyway, I successfully got an image of the drive using GNU_ddrescue (yay!), and I'm currently salvaging what CAN be salvaged with foremost.

way to get EVERYTHING off of the drive? I mean, it seems that it's all intact (since foremost is finding so much stuff).

I've tried mounting the partition, but it's not working. (I'd post the output from the terminal, but the forum thinks there is/are URL(s) in it....)

Fedora :: Data Recovery From Drive On Dead FC4 System

Jun 26, 2009

I have Fedora Core 4 PPTP server (poptop) that died (motherboard). I am setting up a replacement system but need to get the data off of the drive from the dead FC4 system. They are just plain text config files. So I removed the drive and mounted it to another system using a USB enclosure. But I can't mount of the root partition, only the boot partition. I have done some Googling and see that the reason is that the / partition is an LVM format. But of course the replacement system already has a /dev/logvol..... type of partition defined. So how can I mount the LVM partition from the dead system on the new system to get the data? Understanding this will be valuable for similar situations in the future.

Hardware :: Hard Drive Imaging/ Data Recovery?

Feb 22, 2010

I have an hp laptop with 2 hdd slots, both are sata. it came with a 320gb hdd with vista ultimate 64. i added another 320gb hard drive to my laptop and installed kubuntu on the second hard drive. Since vista was my primary hard drive, parts of grub were installed on it i.e. stage 1.5. And the rest was installed on the kubuntu hard drive. Because of that neither os would boot independently of one another.

I eventually got tired of kubuntu and in wanted to uninstall it. I formatted that disk. Now vista gave me grub errors, like I knew it would.I was going to fix the vista boot sector and mbr by running bootrec.exe off of the vista disc. But since I have an hp laptop, hp doesnt provide a recovery disc with just vista, it is an install of the factory image of the os plus software and therefore doesnt have the utilities I need to fix my problem.I ended up navigating to some sort of command line in the windows recovery environment and tried running it there, but no luck.

I tried navigating in the hp recovery environment, and accidently had vista start to reinstall itself on the drive, and actually I did that 3-4 times, each of which I stopped the recovery early on, within 30 seconds, but it had managed to mess up my partition table. I was wondering if there is some utilities in linux/ windows that will help me restore the partitions back the way they should be? I have done a data recovery with get data back for ntfs, and was pretty successful getting some stuff back, figures since the mft was screwed up.

So first of all I want to make an exact clone of the hard drive. Something like dd but just make an image file for now. Since there are no partitions on the drive I dont think I can use partimage, or drive image xml and I wonder if clonezilla will work. And I dont know how to test it without have to reload the image and wiping the drive in the process. I have imaged the drive with get data back but it does me no good cause I cannot restore that image back to the drive, or at least dont think I can.

Second I would like to see if I can recover the partition table , or mft that was over written. Here is a list of programs I can use for imaging or recovering. [URL]Third, since I have 2 320gb hard drives, one that is corrupted, and one that I took kubuntu off of and loaded vista with the recovery disks. Can I take the mbr, and partition table, or boot sector off of the working vista and move it to the broken 320 and fix it that way?

CentOS 5 Hardware :: Hard Disk Crash / Data Recovery In RAID1 Webhosting Server

Feb 1, 2011

We have had a hardisk crash in our RAID1 webhosting server running CentOS5 and Plesk. We first realized something was wrong when our main site didn't load but showed MySQL errors. We then found out that the system was in read-only state. Something that also happened the day before yesterday, but we could fix with a FSCK. Then the system worked well til around 18 hours later when it crashed with the same sympoms. So, we rebooted the server and wanted to do a filesystem check again. But the HDD wouldnt even load. It was gone. Unfortunatelly it was not realized that the second disk in the system was also not working any more for some time now. Fortunatelly we had our main site backed up externally though. So we could re-install a fresh box and mounted the two drives to the system. We checked the harddisk. One is practically empty (the older one), the other has almost only files in 'lost + found' but these are all "numbered", no real filenames or so.

Ubuntu :: Can't Print, Can't Mount USB Drive, And Need Recovery Mode To Log In?

May 10, 2010

A few days ago I began to get messages about my hard drive running out of space, and while I tried to clear out some files to make room I somehow managed to mess something up such that my main login screen appeared with hugely distorted letters and dialog boxes, and it wouldn't let me log in. While this is still the case, I can now log in by booting to recovery mode, selecting the netroot option, doing an "su myusername", and then executing "startx".

While this is a little inconvenient, it does bring up my standard Ubuntu operating environment and I now have access to all my files, email, internet, etc. There are still a few miscellaneous things that are messed up, however, and I don't yet know how to fix themIn particular:a) I can't print. I tried running the printer configuration tool from the System->Administration menu, but there's no "New Printer" icon. Alsowhile trying to get it working, I managed to generate a "The cups scheduler is not running" error message.b) I can't mount a USB drive. Every time I plug one in, I get an error message that says "Unable to mount drive, not authorized."c) Finally, there's the basic problem of still not being able to login without going thru my recovery mode workaround.I suspect all these problems are related, though I'd be happy to fix them one at a time if that's what it takes.

General :: Recovering Data From Ext3 Partition With Hardware Errors - Recovery Required On Readonly Filesystem

Jan 10, 2010

I have an external 3.5" USB 250Gb HDD which is showing symptoms of hardware problems (repeated /var/log/messages errors of "reset high speed USB device using ehci_hcd"). This was originally plugged in to my NSLU2 running Debian Etch. I have just installed Ubuntu Desktop 9.10 to a spare Pentium-3M laptop and was hoping to copy the contents of this HDD to a fresh drive. However, I cannot mount it even read-only; mount -o ro /dev/sde3 /mnt/disk fails, and the /var/log/messages error is "recovery required on readonly filesystem", "write access unavailable, cannot proceed". I cannot understand why mounting a disk read-only should require write access. Following advice I googled elsewhere, I tried running mke2fs -n /dev/sde3 to try to list the alternative superblocks - but once again I got the error that the device was read-only. How can I go about accessing the data on this disk?
