fsck.ext2: No such file or directory while trying to open /dev/mmcnlk0p1
/dev/mmcnlk0p1:
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
Should i now try...
mount /dev/mmcblk0p1 /home/user/MyDocs
Thanks so much for the help guys, i hope the end is in sight and i can get this fixed!
1)
sudo gainroot
2)
umount /dev/mmcblk0p1
3)
fsck.vfat -f /dev/mmcblk0p1
What does each one of this report?

If the last one is giving you too muck questions, you can try what michaaa62 said insted of my number 3:
fsck.vfat -af /dev/mmcblk0p1
this will automatically try to fix without the need to you read anything (mostly).

If you have anything really, really important on the partition you should make a clone copy of the device /dev/mmcblk0p1 to some external storage. From a linux system, either Live-CD or installed system with at least 28 GB free storage available, it would be as root
If things are saved, or you still have the files already copied before, this would write a copy of the superblock of a FAT32 filesystem only back
Note: If that is failing [check with the above fsck code] there is no way back but to rewrite the image your before took, or to knowingly wipe the partition and format it.
Code:
mount /dev/SomePartition /mnt dd if=/dev/YourN900'sFirstPartition of=/mnt/SomeClearName.dd_image bs=4096
Code:
dd if=/dev/mmcblk0p1 of=/dev/mmcblk0p1 bs=512 count=1 skip=6

Heres what i got...
/home/user # umount /dev/mmcblk0p1
umount: cannot umount /dev/mmcblk0p1: Invalid argument
/home/user # fsck.vfat -f /dev/mmcblk0p1
dosfsck 2.11, 12 Mar 2005, FAT32, LFN
Cluster size is zero.
/home/user #
EDIT: Nothing lost yet!

Well, that it usually means that the main sector got corrupted, and that still there's a hope that the backup is still alive, but I have never tried that.
You should do what michaaaa62 just said. Make a image copy, of all your internal drive, (first command) then copy the backup cluster (6) to the main (0) (second commnad) and hope for the best |:/
@Michaaa62:
Are you sure that you are copying the sec 6 to the 0 with this command? Shouldn't I try to copy to the sec 6 somewhere else and then try to copy it to sec 0? I don't know much, but looks like you are copying the 6 to the 6 again, am I wrong?
EDIT:I was wrong. I got it!

Could you really spoon feed me what the final code i should be running is as to avoid messing up my device further please?
Once again i am very thankful for all of you help.
Code:
dd if=/dev/mmcblk0p1 of=/dev/mmcblk0p1 bs=512 count=1 skip=6
the -r option is for after, to the fsck that will be needed after this.

So i should run?...
dd if=/dev/mmcblk0p1 of=/dev/mmcblk0p1 bs=512 count=1 skip=6
Is that the full code? Where would the -r option come in? After i have run this? Thanks again, hopefully its going to be fixable this way!
Code:
dd if=/dev/mmcblk0p1 of=/dev/mmcblk0p1 bs=512 count=1 skip=6
Code:
fsck -af /dev/mmcblk0p1
Code:
fsck -r /dev/mmcblk0p1
Code:
mount /dev/mmcblk0p1 /home/user/MyDocs
The partition for MyDocs is not mounted, this might be often triggered by a corrupted file system due to not being safely removed from a PC.
Please try
