I would think the error results from no file systems found in /dev/mmcblk1, which should be no partition, but a full card. Linux does neither apply nor expect file systems in full devices.

The irritating fact that sfdisk does not note anything about the external card does not look good at all.
I would suggest to try the command once again after a full shutdown including the removal of the battery for a couple of seconds. After boot try to run the sfdisk command on that device only, again.
Code:
sudo gainroot 
sfdisk -l /dev/mmcblk1
If that still does not give any output, try to create the partition table and after a reboot try to create the file system
Code:
sudo gainroot
echo "unit: sectors
> /dev/mmcblk0p1 : start= 16, size= 7554080, Id=c" > table
This a crude estimate for a 4GB card. That size number might be too low, but will not give you an error. You might fine tune later. This command will give you a file, called 'table'. The name has no meaning, but will give you a clue what it is good for. Apply this file to the card as partition table:
Code:
sfdisk  --no-reread /dev/mmcblk1 < table
Any errors? If not, reboot to create the file system, either in HildonFileManager or in X-Terminal
Code:
sudo gainroot 
mkfs.vfat /dev/mmcblk1p1 -n microSD_4GB
You might skip the naming option, if you do not like a label for your devices.

Please interrupt for any errors in the command output!

Viel Erfolg!

did anyone try TestDisk & PhotoRec yet?


EDIT: willi6868, if you have access to an *buntu PC, you might want to try to install those utilities there 1st (if you haven't yet)

So he is recognizing the c but cant read it?

Already tried it on a Windows Vista PC but it is crashing/ have a timeout and doesn't recognizing the memory card after the timeout like every other program/windows explorer I tried..

Looks like a corrupted partition table.

Please try the commands from the earlier post to create the table, then apply it to the card, reboot and hope for the best result...

looks like /dev/mmcblk1 is only in RAM, the card seems not be connected or attached to this device node.
Please try to get some output from the kernel via HAL
Code:
sudo gainroot
lshal | grep volume
lshal | grep Volume
As this is case-sensitive and i am not sure which output to check for the external card please check this for both commands to find any reference to an external card.

Did you recently try to eject the card and re-insert it to avoid possible bad contacts of the card to the port?

Reinserted the memory card before running the commands and my N900 showed me the message 'Speicherkarte beschädigt / damaged memory card'

Looks bad! None of the output is referring to an external card.
Do you have a second card to check the hardware of the N900 for full functionality?
This card seems to be at the end of its life.

Nothing possible anymore?

Sure I have a second one.. Wich commands should I use for it?

No commands, just plug it in, close the lid and see if it works.

I am sorry about the loss of your data. It looked like that after your second post but I was secretly hoping I was wrong.
