N900 internal memory corrupted.. help please - Page 4 - maemo.org

Silly typo, sorry

Code:

dd if=/dev/mmcblk0p1 of=/dev/mmcblk0p1 bs=512 count=1 skip=6

Better use copy and paste for these commands! It is essential to be correct

You put spaces there, there should not be spaces between the "/" and the "dev/[...]".

Looked like there is a space there, but there is not.

My guess is that you have lost your data on this partition. Now, only formatting it |:/

Unless michaaaa62 has a better idea, I would try now

Code:

mkfs.vfat /dev/mmcblk0p1

this should wipe out everything that was in the 27gb part of your phone and make it work |:/

You could try other tools to try to recover the files that were on that, but you looked like they didn't matter after all...

and then, just like michaaa62 said:

checks the filesystem afterwards. It might be necessary to apply some more force to the fsck command that would be

Code:

fsck -r /dev/mmcblk0p1

After you receive no more errors from fsck, you could mount the partition

Code:

mount /dev/mmcblk0p1 /home/user/MyDocs

This will be the final moment of truth, if all went well.

Well you might want to check the partition with testdisk first. It is a well known recovery tool. To get it on your device

Code:

sudo gainroot
apt-get update && apt-get install recovery-tools

This brings in two tools mentioned testdisk and photorec. Use of testdisk:
Little walkthrough:

let it create a 'Fresh Log',
choose your card /dev/mmcblk0,
Intel partition table [if it asks for the info]
Quick Search

You might then try to choose the MyDocs partition, typing 'p' will list the files, arrow keys to get into directories, red entries are deleted files or folders.
If you want to recover them you have to choose a new location for the copy [you are asked for the location, where you want to save it. '.'stands for the current directory you are in, '..' stands for the upper directory.]
Again use the arrow keys to go to the temporary folder for storing the files. There is still the validate question of testdisk, which asks for the location, active in the upper part of the window. Hit 'Y' will copy the file to the new location. [Depending on the size of the file or folder this could take some time. Be patient and let it do its magic]

Good luck!

install backupmenu, and you can acces all your mass storage data and repair it from a linux live cd.

see this

http://talk.maemo.org/showthread.php?t=68620&highlight=partitioning&page =2

- just install backupmenu.
- restart your phone with keyboard open.
- when backupmenu appears connect the n900 to the pc with the live cd.
- then press w and you would get usb mass storage access and SD card storage access too.
- then you can use gparted if you have ubuntu for repair, delete, resize and do anything with your phone partitions.
you can use fsck from there too, that is more useful than do it from maemo
