    Question Ubuntu 12.10 does not recognise working partitions

    Hello guys! I'm back. This was my previous issue. I solved it with dist-upgrading. Currently my system is stable and fast. Kernel 3.7 and nVidia driver 313.

    But after upgrading, my computer was unable to boot anything. GRUB2 you know...
    I've got 3 HDDs in my PC.
    80GB: Ubuntu 12.10/Vista x64
    1TB: data
    500GB: XP/win7/data

    The MBR was stored on the 80GB one, and the Windows MBR was on vista's partition. I use EasyBCD so I was able to get back to grub 1.99 from BOOTMGR.

    After being unable to use my PC, I used a Lenovo repair disc for Win7. I got an MBR to the Win7's partition, and vista was working too. I added in EasyBCD on Win7 the XP and GRUB2 entries, and they work. Currently, my PC starts with BOOTMGR, and I can choose GRUB2 from here.

    So what's my issue?

    Ubuntu doesn't recognise the partitions of the 500GB HDD...
    What can I do? XP and 7 works. All 3 installed types of windows knows what's on the HDD, but linux doesn't. I tryed to CHKDS /b the 3 partitions 500GB HDD but passed, success, and same again.

    Here it is how GParted sees the situation:


    I don't want to lose any data, it's important!

    Please help me if you have any ideas.

    Better to use screen shots and attach with paperclip. Those with slower Internet may have issue with your large pictures.

    Post this:

    sudo fdisk -lu

    Did you change partitions on sdd?
    Does one of the Windows partitions need chkdsk. I once had a working XP install but gparted would not show it. Ran chkdsk, gparted showed it and it booted XP a bit faster.

    This seems not to be a partition table, perhaps you choose the wrong device. (bad translation by me)

    Partitions on sdd are the same for 2,5 years. So no change.
    I ran chkdsk as I mentioned in the first post. With Win7, on the whole sdd.

    The screenshot is 76kbytes, so I don't think it would be an issue...

    Thanks for helping.

    Re: Ubuntu 12.10 does not recognise working partitions

    I am not sure why it is saying that, usually it then does not show a partition table or it looks like random data parsed to be a table. Yours looks ok?

    I might run chkdsk on each partition, not drive.

    Backup partition table to text file & save to external device.
    sudo sfdisk -d /dev/sdd > PTsdd.txt


    And post PTsdd.txt

    Code:
    # partition table of /dev/sdd
    unit: sectors
    
    /dev/sdd1 : start=       63, size=123138162, Id= 7
    /dev/sdd2 : start=123138225, size=853613775, Id= f
    /dev/sdd3 : start=        0, size=        0, Id= 0
    /dev/sdd4 : start=        0, size=        0, Id= 0
    /dev/sdd5 : start=123138288, size=205278507, Id= 7

    You cannot run CHKDSK on a physical disk,(sdd) but on a driver with an available drive letter.
    So I ran them (from the point of win7's view) on C:\, D:\, E:\
    With: chkdsk e: /b

    Re: Ubuntu 12.10 does not recognise working partitions

    I thought it was /r?

    chkdsk c: /r

    You can use the following options:
    /p Does an exhaustive check of the drive and corrects any errors.
    /r Locates bad sectors and recovers readable information.
    Note If you specify the /r option, the /p option is implied. When you specify the chkdsk command without arguments, the command checks the current drive with no options in effect.

    /b
    NTFS only: Clears the list of bad clusters on the volume and rescans all allocated and free clusters for errors. /b includes the functionality of /r. Use this parameter after imaging a volume to a new hard disk drive.
    And /r includes /f. On XP U sed /x in the past, but that's OFF topic.
    WINNT6.x has improved CHKDSK than WINNT5.1.

    Re: Ubuntu 12.10 does not recognise working partitions

    Thanks for the update on chkdsk. I only had XP and never booted with 7 or 8.


    Back to original issue. Partition table still looks ok. Gparted screen is saying something about label. You you have a character that is not recognized? I know once I started using Linux I stopped using spaces, but you may have a foreign character that causes issues?

    Post this to see labels also, post in code tags to preserve format:

    # To clear cache and get new view:
    sudo blkid -c /dev/null -o list


    I know in mounting partitions with fstab we suggest the windows_names option.
    UUID=DA9056C19056A3B3 /media/WinD ntfs defaults,nls=utf8,umask=000,uid=1000,windows_names 0 0
    Window_names prevents the use of invalid windows characters:
    (which are the nine characters ” * / : < > ? \ | and those whose code is less than 0×20)
    uid=1000 should fix the trash problems as well:

    I can't see any of the 500GB WD HDD's partitions...
    The required labels are: none(UUID) for XP, Win7 for Windows7, data for the last one.
    Here the two NTFS partitions called vista and ubuntu, were never used as OS storage. I filled them too quickly, so I had to install these operating systems to an another HDD...

    Is there any partition repair tool on linux, like FSCK, but for NTFS? Maybe it could help if CHKDSK doesn't.
    I ran MBR from Windows partitions before and had no problems on linux...

    Re: Ubuntu 12.10 does not recognise working partitions

    There is or was ntfsfix, but it only does really minor things and sets the chkdsk flag. If flag is set or hibernation flag is set then Linux will not normally mount a NTFS partition.
    Since drive is shown, I assume it is in BIOS. Have you looks with Disk Utility to see if drive has any issues.

    fdisk did show sdd, and showed what looks like good partitions.

    You can try this, just to see what fdisk does. Do not do w if it does not seem ok.
    this occasionally fixes issues and is worth trying:
    you do the following :
    fdisk /dev/sdd
    use option : x (expert mode)
    use option : f (fix partition order)
    use option : r (return)
    use option : p (to print)
    use option : v to verify partition
    if it is ok
    then you can do
    option : w ( to write table to disk)
    option : q to quit
    else if it is not ok
    then post the output of option p and v
