Corrupted EXT3 file system.

[SmartFox]

Hi, guys!
I am using Ubuntu since release 8.10, but it is first time when i can`t solve problem :(

Problems had begun when i tried to create new NTFS partition on unallocated disk space with Paragon Partition Manager (damn, that was stupid). Process was aborted with error (later i finally made it with Gparted without problems)

After reboot mine Ubuntu say:

Errors were found while checking the disk drive for /
Press F to attempt to fix errors, I to ignore, S to skip mounting or M for manual recovery.I pressed "F" but that had help only for a boot and doesn`t really fix error :`(

Later i booted from liveCD and had checked partition (/dev/sdb1; file system - ext3) with gparted (result - aborted fixing process with error)
Now i can`t even boot from that partition and even mount it from other linux system.

mine fdisk -l


/dev/sdb1 * 1 5957 47849568 83 Linux - problematic partition (unmountable)
/dev/sdb2 5958 29983 192988845 7 HPFS/NTFS
/dev/sdb3 29984 113905 674103460+ 7 HPFS/NTFS
/dev/sdb4 113906 121602 61826152+ f W95 Ext'd (LBA)
/dev/sdb5 113906 121602 61819904 83 Linux - fresh ubuntu
When i run "fsck.ext3 /dev/sdb1", result:

fsck.ext3: Group descriptors look bad... trying backup blocks...
/dev/sdb1: clean, 438985/2992416 files, 7558358/11962392 blocksbut it will have no effect...

When i try to mount it - "mount: Stale NFS file handle"

PhotoRec recover most of my files, but i need complete partition.

P.S.: HDD is new - no bad blocks. Help me please, you are my last hope. Sorry for bad English.

Anyone, please say something...

[SciFi-Bob]

Could it be the "max 4 primary partitions" limit?
I have not tried it for some time, and it is possible that there no longer is such a limit, but I remember I had problems in Ubuntu/Debian with more than 4 primary partitions.

Just a thought..

Post this to see if we can see anything.

Some partition managers do not handle Linux partitions well.

Did you try testdisk to see what it saw?

TestDisk exited normally.:(:(:(

[oldfred]

We seem to be seeing a lot of testdisk writing the extended partition beyond the end of the drive. You need to fix that. It may prevent other repairs from running as not being able to correctly read a partition table stops many processes.

I would first backup partition table and save to an external device.

Some have fixed it just by reading the PT.txt file back in. Or editing PT.txt file.

sfdisk to fix extended beyond end -partition outside the disk!
http://ubuntuforums.org/showthread.php?t=1012825

A few have had this work. Not sure what internal process checks sizes.
this occasionally fixes issues and is worth trying:
you do the following :
fdisk /dev/sdb
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


I have not seen:
Stale NFS file handle

[P4man]

Im no expert, but this appears to be a BIOS problem? Can your bios handle such large drives? Is it configured for LBA? Also possible, the hdd is jumpered to limit the capacity to, what is it, 32 or 48GB?

[Spyderkid]

If you don't need the stuff can't you just format it?

oldfred (http://www1.ubuntuforums.org/member.php?u=852711), i fixed overlaping partition error according to the second instruction and i did that:


fdisk /dev/sdb
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

now i have: (fdisk /dev/sdb; option; p)

No guarantees but you could try to force unmounting to release the stale file handle:

umount -f /dev/sdb1*
followed by a reboot.

i have a Western Digital 2.0TB harddrive. was formated with NTFS format and has it just crashed unexpectedly and it has all the data that puts bread on my table.
On mac it needs to be formated when i put it on an Ubuntu and look at it via the Disk utility it says Unknown partition and i can not get anything via it..

when i check the partition table with fdisk -l it looks at the partition
#Disk /dev/sdb doesn't contain a valid partition table#

have tried all sorts of things but heading to no where! if i do not recover this will loose my job.... please help????? Please community people i need your assistance like ASAP!

[matt_symes]

Hi

@edug Try test disc to recover the partition table.

Don't use such a large silly font. It will garner you no friends. And don't hijack threads. Start your own!!

I do not remember now if it was the same or slightly different. I suggested running e2fsck on a partition and it would not unmount. The workaround was to download Slitaz and run the file check from that and it worked.

From liveCD so everything is unmounted,swap off if necessary, change sdb1 to your partition(s)
e2fsck is used to check the ext2/ext3/ext4 family of file systems.
sudo e2fsck -C0 -p -f -v /dev/sdb1
if errors:
sudo e2fsck -f -y -v /dev/sdb1

(i.e., without -a or -p options)
then e2fsck -f -y -v /dev/sdb1 =

If you do not have good backups I would run photorec or similar tools to recover some data.

http://www.cgsecurity.org/wiki/PhotoRec

List backup superblocks:
sudo dumpe2fs /dev/sda5 | grep -i backup
then use backup superblock, 32768 just an example, try several
sudo fsck -b 32768 /dev/sda5

oldfred, it worked!!! I love you, man! :D You saved my files!!! :)

Here's how I did:

1) Using this (http://ubuntuforums.org/showpost.php?p=10434656&postcount=49) instruction i format superblocks, check inodes on partition and rebuilt journal

2) Finally I was able to mount it, but there was only one directory lost+found without any access (even root couldn`t)

3) Then using testdisc i got to "lost+found" (using P to list files) and found container with my home directory

4) And finally simply copied him to other HDD (using C)

problem [SOLVED] :guitar:

[oldfred]

Glad we managed to find something that worked.
