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.

Just now I accidentally used gparted and wiped the partition table on my main hard drive, and now fdisk -l shows nothing! How can i recover my partitions and avoid having to reinstall Gentoo all over again?

I have tried to automate the configuration of a usb drive with not much success.
The problem that I have is that I have a large amount of usb drives that have a partition table of type "loop" and I need to change them to "msdos". The size of the drives vary and I need to use FAT32 or FAT16 file system.
I've tried various partitioning commands and gui applications but cant find one that I can give a one line command to to set the partition table, maximum partition size and file system.

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).

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.

In an attempt to shrink my Data partition on my 500GB drive I had succeded in shrinking it but I think I have broken the partition table as now it refuses to mount. When trying to mount I get this error mount: wrong fs type, bad option, bad superblock on /dev/sda2 I have done some searching around but most fixes haven't worked because they are based on ext2/3 File systems and this partition is ext4. Using Ubuntu 10.04 x64.

a windows installation on a fake-raid, /dev/mapper/ddf1_AR01p1 and an xtra penguinFS on ddf1_AR01p2. I simply tried to boot "Super Grub Virus" from a usb stick ... and the $%!($ER hosed the array. Luckily, my day to day OS and important data is on a different set of disks ... but my BIOS boot target is set to the fake-raid, so it did not kill anything genuinely important ... I just got lucky.
I would really like to restore the windoZe partition as it WAS. I actually use it a couple of times each year. I would just reinstall the OS ... really NOTHING important on those 2 disks, but I have no idea where my XP disk can be found ... but I know the xp installation is hiding in /dev/null ....

Is there a difference between using GPT partition table when formating hard drives and MS-DOS partition table? What are the advantages/disadvantages of using either?

I'm trying to recover movie files from my TNT receiver hard drive but it corrupts its FAT32 allocation table (crappy cheap device...)
Using dosfsck is useless because the correct file length is the cluster length, not the (shorter) one in the table, and dosfsck only proposes to shorten the file, which I won't do.
Question: how to recover a file using the FAT cluster chain instead of using the stored length in the FAT table?

When I start up the thing says "The symbol 'rtoul' not found. Aborting", then it ether boots from a CD, or beeps offensively at me.

I have a GRUB backup pen drive thing, but when I boot from it, it wont accept any keys other than CTRL+ALT+DEL. The partitions can be mounted and are usable, but home is encrypted. I don't want to delete my files.

USB flash disk partition disappeared as well as partition table I'm not sure about the cause
Code:
root@u# less /var/log/syslog
usb 5-1: New USB device found, idVendor=058f, idProduct=1234
usb 5-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[code]....
Where did the partition table go? The device had one ext3 partition something around 4GB(size of USB storage device). I need to restore few files from this device.

A couple of years ago, I got a 2TB drive and installed Debian on it.
I used the standard installation procedure, as I recall, and created three partitions, which are shown below in the output of "fdisk":

I have (had) Debian Testing running on a 250GB IDE hard drive, partitioned normally.
I also have 4x 1TB drives in a raid 5 using mdadm, and 2x 500GB drives in a raid 1 also with mdadm.
I put the two arrays in lvm using:
I then used "lvcreate" to make storage/backup 300GB, and the rest went to storage/media (approx. 2TB usable). I put an xfs filesystem on both and mounted them.
All was working fine until the system drive shorted out and died on me this morning. As far as I can tell, all my other drives and everything else is fine. I do a daily rsnapshot of the filesystem, which of course is residing on storage/backup (stupid, I know). So I have full backups of everything, but I'll have to put a new hard drive in and reinstall Debian before I can restore everything.
I've reinstalled before and simply reassembled mdadm arrays and remounted them before with no problems, but this is the first time I've used lvm, so I'm not sure what I have to do to restore everything. Is it as simple as reinstalling the system then doing a:

I need to find a program or a way to edit the partition table and set the values and addresses for the partition boundaries manually. A while ago I had a very messy data loss that left me with a disk full of data but without a partition table (and without file indexes for some of the partitions on the disk). So, for recovery reasons I need to try lots of combinations of starting and ending addresses for each partition. Additionally it would be extra nice if I could do this with a live cd since I don't have the faulty drive attached to a working computer at the moment.

I was having trouble creating a USB Startup Disk in Ubuntu and used the command:
sudo dd if=/dev/zero of=/dev/sdb bs=1M count=1
This was a mistake as my USB flash drive was on /dev/sdc. If I am understanding this correctly, the command above deleted the MBR and the partition table. This disk had a single "/storage" partition on it. I googled a solution and found that the "testdisk" program seems to be the most popular solution for things like this. I ran it, selected an "Intel/PC partition" type, set the partition to a non-bootable primary Linux partition, wrote it, and rebooted.
Whenever I run:
sudo mount -t ext3 /dev/sdb1 /storage
I get:
mount: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so
Dmesg shows the following:
[20246.273941] EXT3-fs error (device sdb1): ext3_check_descriptors: Block bitmap for group 1 not in group (block 0)!
[20246.279376] EXT3-fs: group descriptors corrupted!
When I run:
sudo fdisk -l /dev/sdb
I get:
Disk /dev/sdb: 400.1 GB, 400088457216 bytes
255 heads, 63 sectors/track, 48641 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

I am trying to install Gentoo. Currently I have windows 7 on my primary Hard Drive.I decided to add in a second HDD that I got for free and use linux on that.I got through my entire install and at the end I accidently wrote grub to my second hard drive.When I rebooted it went straight to windows.So I have some questions. When installing to the secondary HDD does my boot partition and swap need to be on sda? or can they reside on sdb?Also I tried to re-issue the grub-install command and it said bash: command not found. How can I get grub to re-install? I tried to emerge it and same issue no command found.Do I need to redo the entire reinstall?My last question is If I have more then enough HDD space how much is too much for linux? Most people say 30 GB is all you need from what I have read but I assume 160 GB is going to go to waste?

What is the most efficient way to match the partition tables on two different hard disks?
I have saved the partition tables using dd command in linux.
The partition tables are from a Windows system.

This machine has UBUNTU & wINDOWS XP. I'm currently logged into UBUNTU. I was just checking the features of GParted and accidentally clicked Device > Create Partition Table. A default MS-DOS partition table is created. Now if I re-start the Gparted there is nothing. Its showing entire disk as UNALLOCATED space.
Lucky thing is All the drives (C:, D:, E:) are currently mounted and I'm in UBUNTU. I guess its possible to re-create the partition table using current status. how to do this. This is a lab computer. If its not recoverable. I'm completely screwed!

Purpose: Python, PHP, WebKit (hopefully), and pyqt development. There is Wubi for Ubuntu, which I am using right now. But Ubuntu 11.04 doesn't work well with my system. There is a Wubi like installer for Puppy Linux. There is Debian Win32 installer, but I think that does touch the partition table. My last option is to simply grab Ubuntu 10.04 LTS and hope it works. Would that be a viable solution considering my needs?

I've formated partition to empty - only erased information that partition is NTFS.
Partition data haven't been changed. So i think only little change to partition table is required.
How can i recover it?

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).

A HP Netserver LP2000r, with original SCSI controller and HP NetRaid-2M controller, 3x 36GB Ultra3 HDD in RAID5, Debian (sarge/etch), has crashed after 992 days without reboot. From all that I can see, a hardware failure, most likely with the memory. The HP Diagnostic tools cannot find any problem, but everytime I boot into Knoppix, I get between 2minutes and 2 hours of runtime, and then either a kernel oops or just a complete and sudden halt.
Well, the box has earned its money. However, there is some data on the drives that I need to recover (yes, I have beaten myself up properly about not backing up that data, don't even go there !). There are three partitions: sda1 is /, sda2 is swap and sda3 is a LVM volume with 3 logical volumes on it. As far as I can tell, the hardware defect must have been creeping in and has made a total mess of the inodes in all these partitions.
After booting into Knoppix, I can restore the volumes using pvscan, vgscan, lvscan, vgcfgrestore and vgchange. If I try and mount them: mayhem. So I try and check them, using fsck.ext3. All sorts of interesting nonsense, such as a completely empty inode 11 (the first inode) and then obviously from there on all else is pointless. I tried using debugfs, but the information on what to do with it is somewhat spurious.
P.S.: Tomorrow I will go and get myself a 16GB Flash Drive and then hopefully I will be able to dump the partitions one by one onto that drive and transfer the images onto a different computer for analysis and data recovery.
