Software :: Gparted Broken Partition Table?
Jul 4, 2010
While installing Ubuntu I have created 50MB boot partition and was sure is enogugh, but now with growing initrd and kernel size, an autoupdates which were always killed by no sufficient disk space I decided to increase its size. I had following partitions - in disk order:
sda1,primary bootable NTFS, 57GB
sda4, primary ext2, /boot, 47MB
extended sda2{
sda6, ext3, /(root), 43GB
8MB gap
[Code]...
Is the problem still in bad begining of the partition saved or data are already broken ? If the first is there any mount option to really not touch filesystem ? Because I've read even if we mount readonly there are some options saved to disk (as last mount time etc) and I'm aware it could destroy entrie filesystem.
Has the ext3 some partition header as NTFS do? Or is there a way to locate real start of partition? because testdisk and gdisk shows only this one starting sector for sda6. When I moved the sda6 partition there was space between begin of extended partition and begin of sda6, now there is no space, so that's the main reason of suspecting partition begining is in fact over 100MB further.Current partition schema in attached PNG. Also the swap partition was deleted, I don't know when, now there is 4GB hole.

I was reading another thread about someone with a bad partition table and I decided to join this forum. I'm not going to take any drastic actions with the partition (/dev/sda3) in question. I am going to wait for instructions on what to do first. I am not very good with Linux and need some hand holding. System: DELL 4550 Dual-Booted with XP and Ubuntu. Works OK, just no swap. Well, here's what I did: I deleted a partition for Windows XP Pro because it was a trial, and it ran out. I then decided to slide the swap partition for the Ubuntu Linux that I dual-boot into over. (If this was successful, I was going to try expanding the root partition to take up the unused space.) I used Gparted on a CD to do this, as I figured it was safe to do.
I now cannot mount the swap space at bootup (and have to go into a backup version of the OS), although I can use Gparted in Linux to execute the "swapon" command, and it appears that it worked because I now see "swapoff" as an option on the context menu. (I actually don't even need a swap partition, except to hibernate.) If I highlight the swap partition and click on "Drive" on Gparted's menu bar and select "Create Partition Table", it will erase all data on /dev/sda, so how do I fix the bad partition table non-destructively?

I upgraded Windows to 7 from Vista. My Acer laptop had a recovery partition with Vista on it. I don't know, what I was thinking, after the update I deleted the recovery partition. Then got in to problem that Partition Table is deleted. Recovered the partition and partition table with LiveUSB and gpart.
So laptop was working again in about 30mins. Now I see the following issue. Laptop boots and works fine both in Ubuntu (default OS) and Win7. In Disk Utility the partitions are shown as in attachment. In Gparted the disk is not recognized as partition table is not recognized (so I guess) Output of fdisk is here for ref;
Code:
home@home-laptop:~$ sudo fdisk -l
[sudo] password for home:

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!

GParted tells me my hard drive is not partitioned and has an unrecognised partition table, but I know it has because i'm using it now to write this on here, and fdisk shows the following:

Anyone know of anyreason GParted may not be working or can offer an alternative to create a partition?

When I start gparted, to see if I can add extra harddisk where all my data is, I get the next error:
Code:
[root# gparted
libparted : 1.9.0
The kernel was unable to re-read the partition table on /dev/sda (Device or resource busy). This means Linux won't know anything about the modifications you made until you reboot. You should reboot your computer before doing anything with /dev/sda. I can start fedora 12 x64 amd whitout any problem. My partition layout on a single disk (80 gb sata maxtor) for the system is:
Code:
/
/home
swap
When I try to mount one of the extra disks (samsung spinpoint 1 tb, I have 4) I get to next error:
Code:
root# mount /dev/sdb1 /media/sdb1
mount: you must specify the filesystem type
If I add the option with the filesystem I get:
Code:
root# mount -t ext3 /dev/sdb1 /media/sdb1
mount: special device /dev/sdb1 does not exist
In gparted, when I select just a flag option, and deselect, press ok, the disk is forced to be reread by the program. After that I can also mount it. When I use any of the programs linked in this post, I am able to mount the disks whitout any problem. Except after a reboot, I get the same problem. SO whit each reboot, or poweroff, I need to do a re-read of the disks. The system is fedora 12 x64 for amd, installed from a live cd, the rest whit yums groupinstall, the latest kernel.

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.

During a recent request to install fedora 11, I ran into an interesting problem. It seems that between fedora10 and fedora11, the developers switched from fdisk, to parted for creating the initial pre-mke2fs partition table creation.
It looks like the implementation of this is broken, as it's writing the partition table with overlapping cylinder boundaries. While this can sometimes be ignored, it can in certain cases cause significant data corruption.
On an installation I took it through, using the latest installation media, in both manual & automatic partition creation, the layout looked like this:
The last two partitions turn out fine, for some reason. However, those two partitions should not have overlapping cylinders. After my very first installation, the system was completely unbootable, and not even fsck wouldn't rescue it. If this is possible, then that means that a system that's been online for months or even years could simply drop out of functionality simply due to a byte or two of system-critical data falling on that last cylinder. Considering that a lot of the time kernel data ends up on /dev/sda1 (commonly the /boot partition), this is something that should not be ignored.

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 have 3 Ubuntu installations & a PCLINUXOS, plus Windows XP installed on one hard disk. I still can boot to each one of them and can mount each one using Ubuntu.
The problem "may" have occurred when I reduced the size of some linux partitions using gparted. I still have plenty of space in each of those partitions.
When I started gparted all of the HD was unallocated. I did that from each ubuntu installation and the PCLINUX installation, plus LIVECDs. All indicated the space was unallocated.
When I did an fdisk -l from a Puppy Linux LiveCD I got a normal start and ends of each partition.
When I tried it from Ubuntu installation or live cd, I received the following types of responses:
Code:
ubuntu@ubuntu:~$ sudo fdisk -l /dev/sda5
Disk /dev/sda5: 28.5 GB, 28566397440 bytes
255 heads, 63 sectors/track, 3473 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
ubuntu@ubuntu:~$ sudo fdisk -u /dev/sda5
The number of cylinders for this disk is set to 3473.There is nothing wrong with that, but this is larger than 1024,and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Plus the Windows partition seems to go over its limits.
Since all of my OS installations are still working, I don't know how critical this is. From reading another post, I understand this might be able to be fixed by making some changes in fstab.

Theres my fdisk -l:

My harddisk had one extended partition, sda2, split into several logical partitions: da6,sda5,sda7,sda8,sda9 in this order. sda6,sda8,sda9 were [the only] PVs in one [and only] volume group.
I tried to delete sda7 and to resize sda5 (both unrelated to the LVM setup) to take the freed space. I entered both changes in GParted and clicked 'apply'. It gave some error, but had apparently deleted sda7, without resizing sda5. I tried to resize sda5 again, it again gave an error again, but sda5 was resized. I did not save any logs from GParted. Then I saw that the partition names had changed to sda8,sda5,sda6,sda7, in this order.
Now when I run 'vgdisplay', I get the error "Couldn't find device with uuid ....". Running 'blkid' gives the uuids of sda5,sda7,sda9. According to GParted and fdisk, sda9 does not exist. Also, according to blkid, the uuid of sda7 is what used to be the uuid of sda8. I am very confused. As you could expect, I don't have backups, so... (I am now creating a copy of the whole disk, in case things go even more wrong)

I usually repartition a disk by backing up, deleting the partitions, formatting them and repartition. I just did a 200 gig backup (so i am safe) and i want to join 2 (ext3) partition together, sdb1 (data4) and sdb5 (data5) into one big partition. Is there a way to do it without scraping the data in sdb5 (data5). It would save me from rewriting the data back to that new partition (200 gig is time consuming).

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.

Everything is installed and setup on my system, but when I setup my partitions I chose my Windows partition to be bootable. Can I just use cfdisk to toggle the bootable flag so my linux partition is bootable and rewrite the partition table?

Is there a program that will reread the partition table and update the kernel even if one of the unmodified partitions is mounted? I installed my system on one partition, then I added another with free space. Now I want to format the second partition, but the kernel doesn't know about it yet. I tried sfdisk -R /dev/sda, but it refuses while the root partition is mounted. Is there anyway I can avoid rebooting?

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.

I'm trying to clone a Linux install to a different laptop. It's made a little complicated by two facts:
1) The 'new' laptop I'm trying to copy my Linux installation to is actually older and has a smaller hard drive then the computer I'm copying from
2) The computer I'm copying from has both a windows and Linux installation; I only care about the Linux partition.
I figured I would copy only the Linux partition from my primary computer to the laptop, sense the laptop doesn't have a large enough hard drive to copy everything. So I used the DD commands to copy SDA3 (main Linux partition) from my main computer to SDA2 of my laptop. When I came back a few hours later I was surprise to find my laptop trying to reboot itself (I never turned it off). It would keep starting to reboot, failing, and restarting itself. Not too surprising sense its boot partition wasn't changed so it's trying to boot into centos when I copied a redhat partition to it.
The problem is that when I used a redhat boot disk the rescue mode was unable to find a Linux partition to mount. /dev/sda2 exists, but trying to mount it gets the complaint "No such file or directory". "fdisk -l" lists sda1 (the boot sector) and sda2. Sda2 is the correct size and reports Linux LVM for its system. But "fdisk -l /dev/sda2" gives the error message "Disk /dev/sda2 doesn't contain a valid partition table" Did I not clone the drive correctly, or was an error caused due to the boot sector not being copied yet (the laptops boot sector is smaller then my old computers, so I can't copy from old computer to laptop)? Can I salvage the laptops partition table somehow, or do I have to repeat the cloning process? And if I do have to re-clone my computer can anyone tell me what I did wrong the first time so it works this time? I don't care if I copy just the Linux partition or both windows and Linux. Even though my main computer has a larger hard drive I'm only using about half of its available space so it should be possible to copy both partitions if I could ignore the unused sections of the harddrive.
Edit: I used DD to copy a tiny part of the Linux partition from my laptop so I could look at it. Most of it is illegible binary of course, but I scrolled through till I found some text right near the beginning:
Code:
VolGroup00 {
id="F2MWxh-....-BidcLe"
seqno = 1
[code]....
So it seems that the DD command did copy everything over to the laptop, which is good to know. I noticed that it says device="/dev/sda3" right in the middle of the code I just posted. The Linux section of my original computer was SDA3 but I copied it to partition SDA2 of my laptop. So is the problem because the boot partition is for the wrong device? I don't suppose if I modified that one line to say SDA2 it would be able to load correctly? (Not that I know how I would modify the line, short of using the DD command again).

What I believe has happened is that I've corrupted the partition table. Essentially one of my partitions' ending point exceeds the maximum number of cylinders/sectors on my drive.
Essentially I have the same problem as on the thread @ [url] but do not know how to fix this and am afraid to reformat/partition based on sectors without really knowing what I'm doing here.

When I try to look at SDA in GParted everything shows up as unallocated (though it's obviously not) and it says

I installed Ubuntu as shown in the wiki and when I went to restart it gave me a lovely blinking cursor and nothing else. So I held down option, loaded into osx, reinstalled rEFIt and got my menu on startup. Unfortunately, the partition sync tool doesn't seam to be working, it gives me an error: Status: MBR partition table is invalid, partitions overlap. Error: Not Found returned from gptsync.efi

The following is a screenshot of GParted run on my system. There is a small unallocated space at the beginning of the list. This 1 MiB space is kind of annoying and I'd like to merge with any other partition except /dev/sda1, /dev/sda6 and /dev/sda4. When I right click on the unallocated partition, the only available operation is "New". And, if I click on "New", I get the following error message.
It is not possible to create more than 4 primary partitions
how to go about merging the small unallocated space with other partitions?

sda2 and sda5 are the same partition. i set up sda5 because i wanted it to be ext4 just like sda1. i thought if i went ahead and formatted the second partition to ext4 it would just show up, automount and always be there. in my case it hasnt worked that way. is anything wrong with this, if so, how do i fix it?

I have a laptop with a 320GB disk. Windows 7 and Ubuntu 10.04 It has 8 partitions: [From Testdisk]
[code]....
Long story short, after reinstalling windows 7 and messing around a little with its partition and the other ntfs one (resizing etc); Gparted won't open the disk. It shows all the disk as unallocated space, And throws a message to the terminal which says something like "Can't have a partition out of the disk." Funny thing is that *almost* everything is working fine. Everything works except that ubuntu can't use the swap. (Dmesg says: "Swap area shorter than signature indicates") Also, testdisk, if i run a deep search for partitions, finds the last partition twice, but the second time the partition goes from 37129 0 1 to 40240 254 63 , while the disk ends at 38913 255 63. The problem is that I can't use Gparted now and I want to resize a partition.Also I believe that going without swap is not good for ubuntu.

I have a laptop with dual boot and I think because it is a dual boot I can't find the linux partition, installed when I knew nothing about linux, so I most likely went with the default settings, I'm an absolute convert now and have run out of space for ubuntu.So got on the net and seen many screen shots of gparted with a clearly visible linux partition, swap etc, so I make myself a gparted live cd and mine is just not there.Really don't want to do another ubuntu re-install. This k52f has too many setting to correct with ubuntu and took me a really long time!!
Or is there is a different solution to to this other than expanding a possibly hidden linux partition? Is the alternative storing files on a shared partition both os can share?
