1. i switch on the device, then i explore it and start to download some application from the application manager.

2, meanwhiel, I went to the web browser and it sayd " Operations temporarliy disabled due to low memory".

3. when i start reciving SMS messages i see the preview but could not open it as another message appear " close applications".

4. the ovi map can't started and closed immedaility and I can't open any other application.

then i went to the file manager and i want to access the device internal memory "sfil_li_memorycard_internal" a message then appear " Memeory card format unsupported".

i went through setting> phone > memory and i found that a message wirtten under the device "memery card courrupted" and before that probelm it was showen 32GB as it is the internal deviced memeory.

the external momery are shown to be ok.

the solution i think of is to upfdate the softwear and i found that there is no new update using Nokia softwear update. then i just re-update with the same version but NOT SOLVED.

PLEASE ANY SUGGESTION BESID SENDING IT BACK TO THE NOKIA.

the only thing i can do is just using the device to call.

thanx

I have the same problem with my internal phone memory, i tried to restore original settings but that didnt help. And again the mass storage connection doesnt work, so i cannot format the phone,
Any help??
And again, i am new to this linux thing, so i will appreciate your help to be in a simple way

I have the same problem. My phone is one year old, 4 times at Nokia Care 2 weeks every time, and ever repair (I think only reflash it), some days later, damaged again. The last time Care say no more repairs, is my fault. MY FAULT? I like a new one. No, it's your fault.

Thanks Nokia for nothing.

Any solution at this time for this problem?

Thanks in advance, and excuse my poor english.

You need rootsh from extras repository installed for each of these steps in X-Terminal application:
Easiest solution, if you have no data in the MyDocs folder at all, or you could replace the data easily from your PC, apply a fresh new file system to the partition

Code:

sudo gainroot
mkfs.vfat -n MyDocs /dev/mmcblk0p1

If you want to retrieve the data on the phone do not apply a fresh file-system, but check and repair the file-system

Code:

sudo gainroot
fsck -af /dev/mmcblk0p1
mount /dev/mmcblk0p1 /home/user/MyDocs

This might be sufficient to get your data back, but depending of the actual corruption additional steps might be necessary.
Please disconnect the phone really careful from your PC every time, give the two systems (PC and Phone) enough time to sync the writing!!!

Hi michaaa62. Saw your posts in several threads and followed your advise. However, my problem seems a little bit different. Yesterday I lost all my personal data in MyDocs. I do not know why or how - it was definitely before the thunderstorm over Berlin so I can not blame the weather.

Here are the symptoms:

All my personal files on MyDocs (including Easy Debian image etc.) disappeared

However, "new" and empty MyDocs is there

Memory in Settings menu only shows 27 GB internal Memory

So I assume my "old" MyDocs has gone somewhere I have no direct access to

So far testdisk (thank you for the hint) did not help me to retreive my old MyDocs

Further symptom: when tethered to the Mac, no N900 symbol appears on the Mac desktop for N900's internal memory anymore (as it used to be previously) but only an "untiteled" disk.

Any idea how i could retrieve my "old" MyDocs?

Thank you in advance

What does sfdisk -l give you about the card?

Code:

sudo gainroot
sfdisk -l

It took a while until I learned how to create a file withe the output of sfdisk -l (o.k. if you know it, it is really easy, but I am a true greenhorn). Here it is:

Disk /dev/mmcblk0: 977024 cylinders, 4 heads, 16 sectors/track
Units = cylinders of 32768 bytes, blocks of 1024 bytes, counting from 0

Disk /dev/mmcblk1: 120576 cylinders, 4 heads, 16 sectors/track

/dev/mmcblk1p2 0 - 0 0 0 Empty
/dev/mmcblk1p3 0 - 0 0 0 Empty
/dev/mmcblk1p4 0 - 0 0 0 Empty

I am unable to interpret this information. I suspect that mmcblk1 is my 4MB SD-card

Does this information mean anything to you?

This looks okay, the output is your partitiontables from the internal and the external card. MyDocs is just the folder the N900 needs to have some place to mount the internal card to.

But i must admit, i am awfully confused that testdisk failed to recover the files in that partition. Please try to fsck the partition once again

Code:

sudo gainroot
fsck -af /dev/mmcblk0p1

Even try the 'r' option for file-system repairs please

Code:

fsck -r /dev/mmcblk0p1

Thanks again.

My N900 is almost normal: I have a MyDocs Verzeichnis, but it is apparently a new one without those files I saved before some mysterious event yesterday morning - just those files Meamo apparently creates itself if MyDocs is lost.

And: N900 (internal memory) looks different when hooked to the Mac in Massenspeichermodus, no N900 symbol as it used to be until yesterday.

This is what fsck -af delivered:

fsck 1.41.3.maemo0 (12-Oct-2008)
dosfsck 2.11, 12 Mar 2005, FAT32, LFN
Reclaimed 1 unused cluster (16384 bytes) in 1 chain.
Free cluster summary wrong (1768780 vs. really 1768779)
Auto-correcting.
Performing changes.
/dev/mmcblk0p1: 68 files, 84/1768863 clusters

This is what ls -a in MyDocs delivered
