A few months ago I tried to shrink an NTFS partition using gparted and use the free space to install Haiku. However, gparted crashed in the middle of the resize, leading to a corrupt partition table. I tried to solve the problem myself, using testdisk to detect the partitions. However, the fix is not perfect, and it left me with a partition table that goes "outside" of the disk (i.e. the partition table has allocated more sectors than there actually are on the disk to the last partition).
Recently I need to reinstall Ubuntu Natty, but because the partition table is corrupt, the installer on the Ubuntu Natty Live CD (as well as gparted) see the disk as entirely unpartitioned. What is weird is that the Disk Utility (aka palimpsest), fdisk on my current Natty distro (upgraded from Maverick, which I want to replace with a fresh install), and GRUB 2 see the partitions fine (with some errors, such as listing a few trillion TBs of available space, a result of the corrupt partition table).
I am using an Asus U30Jc laptop with a single 500GB HDD. My current setup is supposed to be like this:
/dev/sda1: A hidden FAT32 recovery partition generated by Windows 7, listed as containing Windows Vista by GRUB 2
/dev/sda2: NTFS partition containing Windows 7 (labeled "OS")
/dev/sda3: Extended partition containing "DATA", Ubuntu, swap, and the erroneous trillions of TBs of space
/dev/sda5: NTFS partition containing user data (labeled "DATA")
/dev/sda6: Ext4 partition containing Ubuntu
/dev/sda7: swap partition
(*Though I'm not supposed to have it, and it isn't listed in /dev while running the Live CD, /dev/sda4 exists as a zero-length partition in the output from sfdisk; not sure why)
Currently I've tried the following:
- testdisk, using "deeper search" and writing the partition table back to disk; produced a (usable) partition table that was bad.
- [URL], fsck didn't do much at all, except raise various errors on all partitions except the one containing Natty.
- [URL], tried to substitute the numbers caljohnsmith gave to thegreat with the corresponding values from my run of fdisk -lu, but because caljohnsmith didn't explain where the values came from and what they meant (no offense to him), I was lost; after the last step (setting the end sector on the extended partition to the last cylinder boundary (which I didn't really understand; tell me if you need details on what I did)), gparted went from showing the trillions of TBs of free space as outside all partitions to showing them as inside the extended partition; this also somehow caused the partitions to overlap.(The error parted raises changed from "Error: Can't have a partition outside the disk!" to "Error: Can't have overlapping partitions.

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)

[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.
I opened GParted to create a new partition on a new drive. He wanted me to create a partition table first which I did, and it was created directly without any prompt like im used to see when creating partition. So I recognized too late, that i actually created a MBR on one of my 6 1TB raid5 drives. Not beeing sure if the ne MBR was really written, I have opened ubuntu disk utility and clicked on the check raid button. It directly made a resync. After the resync, mdadm --detail /dev/md0 told me everything is ok and synced. Then I wanted to mount it with:
mount /dev/md0 /mnt Then I get the following error: "mount: wrong fs type, bad option, bad superblock on /dev/md0, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so" I think I just killed my raid5 ;(
I shouldnt work on my server when im tired and when I actually have no time ;( My last hope is the fact, that "Disk Utility" shows that there is a .0 TB ext4 volume on my raid (see screen below) [URL]
I got swap space full error and the ubuntu version of "blue screen of death". I used Disk Utilities to delete a 2.1GB unused partition. When I tried to create a swap space partition (with Disk Utilities) it failed. In the mean time ubuntu did some security updates. When I tried to create again Disk Uilities did not complain but only created a small ~ 500 kB partition. I deleted that and reboot and got "unknown filesystem grub rescue>". I booted from a USB key successfully. Now Disk Utilities and File Browser can see all the partitions and files on the hard drive, but GParted thinks the entire hard drive is unallocated. I vaguely remember that there are two partition table on the hard drive. It may be that one of them was deleted (when I removed the ~ 500 kB partition with Disk Utilities earlier maybe?). It seems at least the other partition table is still intact since Disk Utilities and File Browser can still see all the partitions and files. Is it possible to restore the deleted or damaged partition table and make the hard drive bootable again?

View 5 Replies View RelatedI 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.

After writing the table above I rebooted. Windows prompted me for my restore disk. I rebooted to the live cd again and ran Fdisk.
code....
what I did was: - have NTFS (450GB + 4GB linux-swap + 44GB ext3 with ubuntu 10.10 upgraded from ubuntu 10.4). Ntfs partition contains data only, no windows.
- either with partition magic or paragon I tried to resize the NTFS and since then parted doesn't like my partitions anymore, but Ubuntu boots and works just fine..
- I took the output from fdisk -l and decided to remove the swap partition - ubuntu won't boot saying it needs the swap (although it was never mounted and i deleted the swap while ubuntu was active)
I have the following output from fdisk -l:
Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders

**NOTE: Since the partitions are not on cylinder boundaries, using parted to recreate the partition table may not be good enough.. I don't have a backup of the partition table.
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).
Do i have any chances to restore my windows partition table after tried to install debian and i used the entire disk instead of the free space i had alocated for this

I have a laptop with 250 GB SATA HD that has the following:
Win7 Pro installed first with sda1=system reserved partition, sda2=C: drive, sda5=separate software application programs to differentiate from Windows' Program Files. Ubuntu 9.10 was installed next (sda6=common swap partition for all Linux distros, sda7=Ubuntu root, sda8=Ubuntu home). Then Opensuse 11.2 was installed with sda12=root and sda13=home. Finally FedoraCore11 was installed with sda9=boot, sda10=root and sda11=home. Ubuntu and Suse have grub loader in their own root partitions.
Suse's grub menu controls all OS's. From this grub menu I can select Windows or any other Linuxes. Suse uses legacy grub because it was installed right after Ubuntu 9.10 which uses (legacy) grub.
Here is opensuse's grub menu:

I am using a 8 GB usb flash to create a F13 Live Media. I created it using the livecd-creator. But when I use it to try to boot, it says "No bootable partition in table". What's wrong? I did some searches on google, but didn't find a solution.
View 7 Replies View RelatedI'm trying to install Fedora 10 from a USB memory stick on which i've installed Fedora-10-x86_64-DVD.iso and, early in the process of configuring the installation, i get messages about both my IDE hard drives having unrecognizable partition tables:
"The partition table on device sda (... my disk data ...) was unreadable. To create new partitions it must be initialized, causing the loss of ALL DATA on this drive."
Same for sdb.
My PC currently runs Fedora Core 4 (yes i know i should have gotten around to upgrading my OS earlier) and yes it recognizes both hard drives just fine.
The answers I've found on the web suggest to backup my drives and repartition. I'm not too hot on that "solution".
explain why a F4 partition table is not recognized by F10?
BTW, I've recently upgraded my motherboard, processor, DVD drive, regrouped both my IDE drives on the same bus, ... I consider it a miracle F4 still runs on this PC (although F4 does not support the motherboard's graphics card, so no X11).

View 2 Replies View RelatedI have a Toshiba laptop, running Vista Home Premium SP2 with AMD Athlon 64 X2 Dual-Core Processor, 1 gb ram & 150 gb HDD. I just shrunk the c: drive down to 92 gb to free up 43.5 gb so as to load the Fedora Linux OS into this free space & have a dual-boot configur'n. My problem is the partition table in the MBR. It shows 4 partitions there, so the fedora 13 Live CD which I use to install the OS cannot find a free spot in the partition table. I have the Ultimate Boot CD so I took a look at the MBR. Here are the 4 partitions that occupies its table:
1. (no drive letter) - file system: blank - EISA config'n - 1.46 gb - partition type code: x27
2. C: - fs: ntfs - system, boot, active, primary partition - 92.01 gb - code: x07
3. D: - fs: ntfs - primary - 5.98 gb - code: x07
4. (no drive letter) - fs: blank - primary - 5.64 gb - code: x17
c: is 17% free, d: is 99% free, the other two are 100% free Can you explain what is the purpose of D: ? How about the other two (with no drive letter)? I read somewhere that 'x17' code means 'hidden IFS (ex: HPFS)' & 'x27' means a rescue partition... true?
Would I be safe in replacing the partition table entry for #1, 3 or 4 with an entry for my Linux? (I have an editor that could modify the MBR). Or would it be better to leave MBR alone, put a boot program on a CD or USB stick, which boots Linux from the unallocated 'partition'? (have to somehow manually install Linux to the 43.5 gb area that I freed up).
1.After I install fedora14, I can not start window7,It shows only a transverse line shining .
2.when I comes into inux , execute "fdisk-l " ,it shows 'no invalid partition table' this two points have relationship?
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.
Will deleting dev/sda partition table ( msdos ) affect my windows 7 system? I am trying to install Fedora 15 on Virtual Box.

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:

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.
