    Partition table errors -> unallocated for GPartEd

    Hi all,

    I have a minor problem with my partition table (dual boot). "Minor" because I can still boot and everything, the only consequence as far as I'm aware is that GPartEd does not see the partitions (latest GpartEd, 0.12.1).

    I have now read a fair amount of threads about similar problems but could not find a way to fix it (without re-installing everything, I don't want to currently).

    Here is the bootinfoscript output:

    Code:
                     Boot Info Script 0.61      [1 April 2012]
    
    
    ============================= Boot Info Summary: ===============================
    
     => Grub2 (v1.97-1.98) is installed in the MBR of /dev/sda and looks at sector 
        1 of the same hard drive for core.img. core.img is at this location and 
        looks in partition 7 for (,msdos7)/boot/grub.
     => Windows is installed in the MBR of /dev/sdb.

    a few precisions about the 3 first partitions, in case you want to know:

    1. manufacturer recovery software (Samsung laptop). didn't want to remove this, in order to be able to go back to the original state (even if I actually also have PartImage backups)
    2. the useless Windows hidden partition
    3. the actual Windows 7


    Also don't be surprised with the number of (extended) partitions, I like to organize my disk this way.

    I have already tried to write the table again with fdisk, didn't work. btw I would be interested in understanding why fdisk can show something different from what is actually in the table?

    Thank you!

    Re: Partition table errors -> unallocated for GPartEd

    I cannot see an issue & script often highlights an error in partition table.

    What does gparted show? Do you see partitions but errors or warning icons. If you click on those it will tell you more about the issue.

    I have had gparted not even show my drive. I had XP installed and it was working, but gparted would take forever to try to mount then just show my other drives. I ran chkdsk, Windows actually booted a bit faster and then gparted worked.

    Just a comment or two.
    I do not like FAT anymore for larger partitions or partitions on a hard drive. (Unless you absolutely have to have it for some compatibility reason wtih Mac or Xbox.) I thought I was creating backups but they were over 4GB and every one was exactly 4GB. It turns out that is the max file size in FAT32, so I never had a valid backup. Converted to NTFS for data I needed with XP and ext4 for backup data. FAT32 also does not have a journal, so file recovery can be more difficult or impossible where with NTFS it might be.
    With multiple drives I prefer to have each system on a separate drive. Drives fail and I like to have at least one drive bootable, but I also have multiple bootable flash drives with Ubuntu, repair ISOs and other ISO.

    Re: Partition table errors -> unallocated for GPartEd

    For Gparted the whole disk is "unallocated space", no partitions at all.

    Yes I know the FAT32 limitation. until now I wasn't sure if NTFS was properly supported by most Linux tools, which is why my "shared partition" is still FAT32.
    About multiple drives, this is a laptop so wouldn't be really convenient here

    Thanks for the comments anyway

    Re: Partition table errors -> unallocated for GPartEd

    I think the issue was there in 2006 when I used FAT32, but I changed to NTFS in 2009 and not had any issues. Most that have issues use hibernation and that was not the NTFS driver but an issue trying to use two systems to write into the same space.

    I might try chkdsk from a Windows repair CD on every NTFS & FAT32 partition. Not sure what else may be the issue.

    Did you change BIOS to turn RAID on? That might write a setting that gparted would not be compatible with, but that normally is before any install and drive has RAID settings left.

    Re: Partition table errors -> unallocated for GPartEd

    ok thanks for the tip about FAT32/NTFS.

    Don't have any windows CD but did a chkdsk from windows, no error found.

    Did not change anything in the BIOS (and btw I forgot to say that GParted used to work fine with my disk)

    Other ideas? Do you think it looks more like a real error or a bug in Gparted? Because in the latter case I can live with that, and later when I want to re-install everything I will re-create all my partitions.

    Re: Partition table errors -> unallocated for GPartEd

    I do not see anything wrong other than these comments in your recovery & FAT partitions.

    I know NTFS - PBR (partition boot sector) has to have the same start & size info as the partition table. I am not sure about FAT but bet it does also.

    Boot sector info: According to the info in the boot sector, sda1 has
    31457279 sectors, but according to the info from
    fdisk, it has 31465471 sectors.

    Boot sector info: According to the info in the boot sector, sda5 starts
    at sector 0. But according to the info from fdisk,
    sda5 starts at sector 136118871.

    IS FAT sdb1:
    Boot file info: Grub2 (v1.97-1.98) in the file
    /120701-temp-backup-MBR-with-errors.img looks at
    sector 1 of the same hard drive for core.img, but
    core.img can not be found at this location.

    With NTFS a chkdsk or fixBoot is required to fix PBR.
    Not sure how the fix the FAT partition with grub2 install since now Windows will not recognize it as a FAT partition.

    This says the recovery is the same for FAT32.

    Recovery of a FAT32 partition (instead of an NTFS partition) can be accomplished by following exactly the same steps.

    Do you know if it's possible to run chkdisk or fixboot without a Windows CD?

    This says the recovery is the same for FAT32.
    http://www.cgsecurity.org/wiki/TestDisk_Step_By_Step
    testdisk didn't help me because it does not find any problem to fix: as far as I understand you can only write a new partition table if some partition recovery was done before.

    Do you know someone with the some 32 or 64 bit version of Windows?

    We used to recommend Neosmart as they had a free download for the Windows repairs. They were offline for a while & I now see they want $10 for the download. So make one yourself before you have to pay to get one.

    Re: Partition table errors -> unallocated for GPartEd

    Sorry for the delay, since everything was still working I didn't want to break anything before being ready to deal with it.

    So recently after doing my backups I tried to rebuild the partitions with testdisk... didn't work. My understanding is that there was some kind of inconsistency with the partition table: I strongly suspect the first partition with the "Samsung Recovery" system, because as far as I understand it has some hidden sectors and probably I did something wrong about that with grub or soem other tool.

    So basically I ended reinstalling everything: since I wanted to get rid of both this recovery partition and the Windows "hidden" boot partition, I found these useful pieces of information:
    1. you can download a windows install CD legally: http://www.pcworld.com/article/24899..._the_disc.html
    2. and you can simply avoid creating the windows hidden partition: http://www.mydigitallife.info/how-to...7-installation


    and I installed Ubuntu 12.04, but unfortunately I now have another problem... for which I started this new thread (since it's not related to this one):

    http://ubuntuforums.org/showthread.php?p=12113397

    Anyway thank you very much for your help!
