memory corrupt
 

hey people
this is my first post here.
well, my n900 memory is corrupt and in the country where i am now, they dont know how to solve my problem .
i have got a lot of posts about this problem, but i didnt fealy understand anything.
they were using words like emmc and other sutff i dont know.
please tell me how to do it step by step how to get back my stuff.
and is it rely posible to repare my n900 internal memory card ??

Re: memory corrupt
 

right now i can access to my contacts, my apps .

Can you take photo's with the camera and video anything?

Re: memory corrupt
 

First : It is possible to repair some things from the device itself before trying to reflash and therefore remove your files. You need rootsh installed to become root in a X-Terminal. So install it from Application Manager. Open X-Terminal and become root You might try to check the filesystemThen remount MyDocsIf no errors show up, you might now be ready to roll again, if not please post here with the error messages.

Re: memory corrupt
 

thanks alot
i have got an error . here it is everything .

Re: memory corrupt
 

Did you change the partition setup? This looks really fishy.

Please paste the output of If you lost the MyDocs partition, may be testdisk can recover it for you.

Re: memory corrupt
 

do you mean i just copy and paste the code ??


i copied and pasted the code and this is the output :

Re: memory corrupt
 

Okay, the content of your /home/user is fine, even MyDocs is there and fine(permissions et al.)
Please become root (missed to mention it, sorry) to have the output of mount does indicate the missing partition to be mounted to MyDocs.
df -k is irrelavant if /dev/mmcblk0p1 is not mounted properly

i posted the fisrt code ( the ne u forgot ) and here is the output :

Re: memory corrupt
 

Okay, now try to mount the partition after checking the filesystemMost of the times fsck guesses the right tweaks the filesystem needs. Sometimes the '-r' option might be necessary instead of '-f'.
Then mount MyDocs .
All must be done by root (sudo gainroot)

Re: memory corrupt
 

Is this a 'read only file system' error?
Were you downloading anything large or using transmission by any chance when this first occurred?

Re: memory corrupt
 

i dont know if it is read only or anythin.i dont remember exactly wt i was doing but i think i was sending a movie from my laptop .

here is the out put of michaaa62's code

Re: memory corrupt
 

i tried fsck -r but online one line is given
wt else should i do ?? .

Re: memory corrupt
 

by the way. when i connect it to the computer it shows the drive but when i click on it it says , please enter Drive (E) .

Re: memory corrupt
 

but i can browse the internet and i can install someprograms from the app magaer.

please tell if it is going to be fine . please . i realy want to get it back

Re: memory corrupt
 

Working on a solution, just some more testing here. Will be back in an hour, hopefully.

Re: memory corrupt
 

ok .
thanks

Re: memory corrupt
 

Hope this will work:
To simulate your situation i just zero'ed the first sector of my external card to reproduce the error message, then copied the backup sector of the filesystem to the first sector. This made a filesystem check possible and all of my data readable again.

Re: memory corrupt
 

okay . so should i enter an external memory card ??

Re: memory corrupt
 

i pasted ur code . before i enter a memory card .

now when ever i enter
sudo getroot
it says : password : and i cant write anything else

wt should i do ?

Re: memory corrupt
 

correct one is "sudo gainroot" not "sudo getroot"

Re: memory corrupt
 

wt else to do ??

Re: memory corrupt
 

No external card necessary that was just available here for testing and as freemangordon correctly notes:

Re: memory corrupt
 

owww . yea . i am sorry , i dont know anything about these comands . i corrected it and i wrote the output . is it showing that everything is going fine ??

Re: memory corrupt
 

should be wrong, Please try instead.

Re: memory corrupt
 

keep running the set of codes a few times till you get no errors. it usually takes 3/4 runs of the code...

Re: memory corrupt
 

Looks like you're almost there.... try this:

If it fails to mount again, one thing to try: Connect it to a computer (you seem to have one available?) and see if you can then see the data. If you can, I would make a copy of the data elsewhere, just in case.

If the I/O error is an indication, it may be your are having flash failure. It's unlikely, but possible. If so, a reformat (with bad cluster check) may solve it and make it usable again, but that will erase all data.

Re: memory corrupt
 

nothing has happened . i still cant access my folders.
i retarted my phone and nothing has happened .
from the output . wt did u realize . is everything going ok or there is something wrong ??

Re: memory corrupt
 

I would not think something is lost.
What is the error of the above fsck commands please?

Re: memory corrupt
 

sorry i didnt see ur last post .
ok . does it usually takes time to mount ??
couz i didnt see any error

Re: memory corrupt
 

thanks alot . now it is working !!!!!!!!!!!!!!!!!!!!!!!!

Re: memory corrupt
 

Can you run this code and show the output? (Don't need the column of numbers from fsck, but otherwise output is desired.)

The | character may be hard to find. Hit (Func/blue-arrow) followed by (Sym/Ctrl) to get the special keyboard to type it.

Edit:
Lol... Never mind, see it's working now! Do make a backup as quick as you can. Also, you may want to post the answer to this:

If it was bad memory block, this could happen again unless you reformat and check it to remove the bad block.
