Try fsck with a backup superblock, that might give you a fair chance.
To list the backups of the superblock created during initial make of the file system do:
You will receive a table containing your superblocks. They are different than my example:
Then pick up one of the superblocks and hand it with the -b option to fsck. From my example it would be
Hope it get you further on that problematic partition.
To list the backups of the superblock created during initial make of the file system do:
Code:
sudo gainroot dumpe2fs /dev/mmcblk0p2 | grep -i superblock
[1|root@Nokia-N900|~]dumpe2fs /dev/mmcblk0p2 | grep -i superblock
dumpe2fs 1.41.3.maemo0 (12-Oct-2008)

It gave me "unable to set superblock flags on /dev/mmcblk0p2"
Is that hardware problem?
And another question.... mmcblk0p2 is a part of internal EMMC?
Is there any solution?
Thx again...

I want to encourage you to not write down the error messages or to describe them, but copy and paste them please, because these error messages are meaningful!
If you are somehow unable to paste things here please redirect the output of the commands to a file and attach it here. The redirection writes nothing to the screen, so every command seems to die silently, but it is writing the output to a file.
Example:
The first command works as usual, the second one creates the file partitiontable.txt and redirects the output of the 'sfdisk -l' command to it.
Please attach the partitiontable.txt from the above example here!

Sorry to ask again!
Could you please attach the partition table as in post #5 above?
Also try to format the partition again, IF no data is on that partition, that would be destroyed.

Thanks in advance
I posted many threads in this forum for two months explaining that i've problem with my EMMC, However i could see the original size of it "27GB MyDocs and 5GB Applicable memory"
I think i know where's the problem now
After i applied this thread on wiki :http://wiki.maemo.org/Repartitioning..._compatible.29
I entered this command line and i got this error "mounting /dev/mmcblk0p2 on /mnt failed: Invalid argument"
I tried this "mount -t ext3 /dev/mmcblk0p2 /mnt"
Gave me "Invalid argument"
I tried this "fsck -af /dev/mmcblk0p2"
and it gave me "unable to set superlock flags on /dev/mmcblk0p2"
I saw this error while restoring backupmenu image too.
Any help?
