Ubuntu :: Fixing A Deleted Partition Table / Data Recovery?

Jan 27, 2010

I erased my partition table. Can anyone recommend a good method of reconstructing it? And if this is impossible, can anyone recommend a good method of data recovery? I had an ntfs partition with windows 7 and a larger ext3 partition that ran Debian.

I'm running Test-disk on the SystemRescueCD at the moment (cross your fingers).

Hardware :: Restore Partition Table Or Recover Data?

Mar 27, 2009

I was putting the cover back on my Antec p180b, and I guess it got stuck and gave it a hard bump (pretty much broke the cover). As a result, one of my hard drives, a Seagate Barracuda ST3750640AS, got messed up or something. All the other hard drives are fine. It's in an LVM with another hard drive, so now I can't boot up into my computer. So I booted into the installation CD:

Code:

# find /dev/sd[a-c][1-3]
/dev/sda1
/dev/sda2

[code]....

This led me to believe the partition was messed up. So I ran cfdisk, and it said something about a missing partition table or something. Additionally, instead of showing the single partition on it, it displays, from my recollection, Pri*Log. To my knowledge, this is the only problem with the hard drive. So now I need to either somehow create or restore the partition table without overwriting the data. Or get a new hard drive, and some how recover the data (LVM, partitions, and all).

Software :: Repair Missing Partition Table And Recover Data From Xfs?

Jun 15, 2009

I used to have a 1TB external drive with lots of stuff on it. But after a reported drive failure during a F11 install the partition table seems to have been lost. (I think F11 toasted it)

Disk /dev/sdc: 1000.2 GB, 1000215724032 bytes
255 heads, 63 sectors/track, 121602 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

[code]....

The drive used to have xfs and a partition. Is there any way to rebuild the partition? Or is my 1TB of data gone forever? The drives seem to be fine now... I just want to get it up enough to either pull any data or just to get a file list. Most of the stuff on the drive was from somewhere else.(ie 300GB of NRN data for all of North America.

Ubuntu :: Partition Table Was Deleted / Cant Restore?

Mar 2, 2010

I was working on creating a partition on a new hard drive I was planning on using for storage. I wasn't paying attention and chose to delete the partition on my master. I am running a dual boot with Vista and Ubuntu. When I rebooted It will only go to the Grub> prompt. Ive ran TestDisk and though that I had corrected the problem but it didnt. After running TestDisk again here is what It came up with.

Disk /dev/sda - 320 GB / 298 GiB - CHS 38914 255 63
Partition Start End Size in sectors
L HPFS - NTFS 0 32 33 28554 254 63 458734027
L Linux 28555 1 1 38585 254 63 161147952
L Linux Swap 38586 1 1 38912 254 63 5253192
Structure: Ok. Use Up/Down Arrow keys to select partition.
Use Left/Right Arrow keys to CHANGE partition characteristics:
code....

After writing the table above I rebooted. Windows prompted me for my restore disk. I rebooted to the live cd again and ran Fdisk.

General :: Deleted Root Directory - How To Recover System Data

Feb 27, 2010

I have accidentally ended up in deleting my root directory while I blindly fired command while watching movie.

I fired following command
#rm -rf ~/<SPACE>*.out
instead of this command
#rm -rf ~/*.out

Things already done:
1) Created /root directory relogged to get some of basic settings of gnome and Desktop.
2) Things went well now when I login my desktop ,gnome environment and other things looks to be working well only prompt on my terminal has changed. I can fix it any ways.

Things I want to ask:
1) I haven't studied much about contents of /root directory to best of my knowledge is it like other user's home directory with some basic configuration files for mostly required applications. SO my question is have I lost any thing important system file or something?
2) If I have lost any important configuration or system data how can I recover it without reinstalling whole system? (My opinion about this is, It is quite possible but to do so, as far as I know capabilities of linux. But I still want comments from experts before I try any things on it because I don't want to backup my whole HDD and reinstall the whole stuff again for me and also my sister's stuff in MS.)

Hardware :: Recover Data From RAID 0 From Win XP?

Apr 23, 2009

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...

Ubuntu Installation :: Accidentally Deleted Partition Table On Lvm Physical Volume.

Jul 18, 2010

I was trying to remove the physical volume from an old drive. So I opened gparted and told it to rewrite the partition table. The only problem is I targeted the wrong volume, I wiped the partition table on my 4tb raid5 array This 4tb array has everything! All my movies, tv shows, music. The only things I have backup up off site are my smaller files like documents. I was about to lose my whole media collection.

I did some research and found a solution that I will post here in the hopes that someone will google "I deleted the partition table on my lvm" and be find the solution.You should find in your filesystem a /etc/lvm/backup folder. LVM puts a copy of the crucial lvm information there every time you change the the volume group.

In this folder you will find a file for each volume group. In this file you will find the uuid for all of the physical volumes that make up that group.The first step is to recreate each physical volume with their original uuids. In my case I had only 1 physical volume, which was my raid5 array. My recreation command looked like this:

pvcreate --uuid cLrY02-zrVi-D0Vi-cIPB-6fF5-ed0c-XFF0os /dev/md0

Now I have a physical volume with the same uuid it had before. It is essential that you correctly match up the uuids with the correct physical deviecs.The recreated pv is empty, the volume group needs to be recovered. This is done by using a special tool and the backup file. For me the command looked like this:

vgcfgrestore --file /etc/lvm/backup/raid5 raid5

This tells it to recreate the volume group using the information in the backup file. The backup files looks for the uuid of the PV, which now matches the correct volume. The coordinates in the backup file match up to the data on the array an suddenly everything is back!

When I deleted my LVM partition table I did not damage any of the actual volumes on the volume group, I just wiped out the table of contents. The backup file had the information needed to rewrite this table of contents.

Hardware :: Recover Data From Raid 1 Drive?

Oct 17, 2010

I was using a Buffalo LinkStation Duo to store pictures and the OS in the unit failed. As far as I know, the data on the two 1 TB drives is fine, and since Buffalo uses a Linux kernel in their LinkStation and the format is xfs, it should be possible to get the data off if I can mount one of the drives on a Linux box. I've put one of the drives into an external USB enclosure and attached it to my Linux system, but I cannot get the drive to mount, probably because it is one element of a Raid 1 array.

Most of what I can find on the Web concerns setting up a new Raid array, not creating an array around a drive that already contains data. I have installed mdadm, and I'm running Mint Linux release 9 (Isadora) on an Intel box. When I run mdadm -D /dev/sdb or sdb6, the device and the partition where the data is located, it reports that the device does not appear to be an md device. I'm not sure what that means. Any help would be greatly appreciated, as I've got around 13,000 photos on these disks that have no backup (I figured what could go wrong with mirrored copies?).

General :: Recover From Deleted Ext2 Partition?

May 3, 2010

I was installing windows vista on my computer, so I backed up everything to a external drive which was formatted with ext2. I then proceeded to install windows vista. When I got to the partition section I tried installing windows vista to my raid 0. When it didn't work I decided that I would delete all my existing partitions and create a new one. Well in my haste I accidentally deleted my ext2 partition from my backup drive that was still connected. As soon as I realized what I had done I shutdown the windows install and disconnected my external drive. This is the current state of my drive from parted:

Model: WD 15EADS External (scsi)
Disk /dev/sdb: 1500GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Number Start End Size Type File system Flags

I know that the drive only had one partition before and that it took up the entire disk and it was ext2 (maybe ext3).

General :: Recover Partition-Table Still Present In Running System?

Dec 1, 2010

I accidentially overwrote the first 1M of my harddisk on linux (using dd). So, the partition-table is gone. I can still access all partition (except the first one) using /dev/sda2 (and so on), so the data is still there. I only need the partition boundaries to restore the table. How can I do this? The Linux-Kernel must still know them because all mount-points still work. fdisk -l /dev/sda doesn't work because it acctualy reads the partition table.

Server :: Mount Raid Device To Recover Data?

Aug 20, 2009

In a nutshell, our RAID 1 array was rendered broken and we were advised that core lib files were missing and the OS needed to be reloaded... a quote from our server host:"The OS is not healthy.This server will need a reinstall.
Libs are missing." This was after having replaced what we though was a faulty /dev/sdb. So they reloaded the OS (Debian 5.0.2 x86_64) on 2 FRESH drives, and installed the old /dev/sda as /dev/sdc once the reload was completed. Here's the output of /etc/fstab on the fresh install so we know what we're working with:

Code:

debian:/BAK# cat /etc/fstab
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>

[code]....

The one problem I see myself running into is /dev/md1 and /dev/md2 are currently in use by the new system, so I cannot mount it there. I should also note, reloading the OS is a viable option if needed as we haven't started configuring the server yet. So if we need to reinstall the OS and assign the NEW RAID arrays to something other than /dev/md1 and /dev/md2 then we can do that.

CentOS 5 :: Unable To Recover Deleted Files From Ext3 Partition?

Feb 10, 2011

I am using CentOS 5.5.I suppose this is an oft repeated question. I accidentally deleted, using rm command, 2 wmv files. The files were in a single ext3 1Tb drive, with just 1 partition --- the ext3 one. Each file is 600 - 800mb. The 1Tb drive has only about 20Gb data.Immediately after deleting the files i unmounted the drive (/dev/sdc1). Thereafter i searched the the net and came to know of the recovery tools foremost and photorec. I have installed both of them. I am currently running both of them as root --- foremost is just showing a lot of * signs on the terminal and photorec has managed to find some txt and png files --- but no wmv.For foremost i used: /usr/sbin/foremost -t wmv -i /dev/sdc1For photorec i followed some instructions available on the web.

In the meantime, based on some post on the net i ran debugfs as root, then cd into the directory where the files were deleted. Then on typing ls -d i managed to get the inodes of the 2 deleted files and the names of the deleted files are also correct. The instructions on the net http://www.theavidcoder.com/?p=3 tell me to run fsstat and dls both of which i am unable to find in /bin, /usr/bin, /usr/sbin and /sbin. So i am unable to proceed further.

SUSE :: Deleted Grub Loader And Partition - Recover Boot To Load Windows 7?

Oct 25, 2010

I let a 'friend' use my laptop over the weekend. Now when I turn it on, it loads the BIOS details, then says no active partition, then no OS cannot be found.

It looks like they have deleted the partition with SuSE with the Grub Loader.

I cannot load up SuSE or Windows 7!

Any ideas on how to recover the boot to load Windows 7?

I have tried using the Windows 7 install disc to repair - but it does not recognise that Windows is installed and wants to do a clean install only.

Is it worth trying to reinstall SuSE and hope it detects Windows on the other partition? (I assume it is still there!)

I cannot get to a command prompt.

Ubuntu :: Recover Data Off The 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?

CentOS 5 Hardware :: Using Asus P6T Built-in Intel RAID - CPU Fan Fails And The System Halts - Recover Data?

Jan 20, 2011

The situation: computer based on Asus P6T motherboard. Two RAIDS:

- 'boot', on motherboard built-in RAID controller (CentOS 5.5 installed on this RAID)
- 'data' on 3dware RAID card

At one moment a CPU fan fails and the system halts. After the fan is replaced, BIOS informs it's reset and all the inner controller data are forgotten. After I switch it to 'RAID' mode, it remembers it was a mirror raid (RAID 1) installed, but the file system on it is completely trashed.

The 'data' RAID run by external controller isn't affected by the system failure. Three questions:

- is it worth trying to install OS on the rebuilt 'boot' RAID once again? Looks like if BIOS settings are lost for some reason, there's chance of completely losing RAID data
- has someone encountered similar problem with built-in RAID nd was it possible to recover data?
- will the software RAID be worth creating instead of using hardware RAID to replace the 'boot' drive?

Hardware :: Recover Data On Ext3 Partition On Ubuntu?

Apr 25, 2009

I wanted to upgrade from Intrepid to Jaunty. I opted for a format/reinstall as I figured upgrading usually sucks. To save my important data, I resized my partition (partition A), formatted the empty space with ext3 (now partition B), and moved the necessary files from partition A to partition B. Then I went through the install process and installed Jaunty on partition A, telling the installer to NOT format partition B. It gave a warning about the installer deleting system folders (var, usr, etc) but I figured it didn't apply. I was wrong.

So now partition B is "empty." I know it didn't format it, but I need to get those files off of there. I have created an image of partition B using ddrescue, but I don't know where to go from there. I tried using foremost, but it won't recover things like my virtual machines and completely nukes the original file structure I had. And I've tried mounting it (using sudo mount -t ext3 -o loop /home/user/recovery.img /mnt), but that doesn't seem to work. The mount command completes successfully, but nothing shows up in the folder I mounted it to.

Debian :: Recovering Data From Deleted Partition

May 16, 2010

I was trying to delete a logical drive in windows xp and the damn disk management tool in windows not only deleted my other windows partition but also my linux /data ext3 partition. Now I have a unallocated space in place of these partitions. The data is still there but the entries in the partition table have been removed. So how do I recover my partition. I was trying to use the following tutorial. [URK]

I used the sudo parted /dev/sda -- and then rescue START END command and could get back the /data partition. But it gives me the following error while mounting the partition. mount: wrong fs type, bad option, bad superblock on /dev/sda7, missing codepage or helper program or other error. In some cases useful info is found in syslog - try dmesg | tail or so.

What does this mean. How to I fix this? Also when I try to recover my windows partition using parted it scans for a while and then does nothing. It doesnot ask for writing the lost partition in the partition table. What do I do?
