You need rootsh installed from extras repository to check the file system from X-Terminal
Code:
sudo gainroot
umount /dev/mmcblk0p1
fsck -af /dev/mmcblk0p1
mount /dev/mmcblk0p1 /home/user/MyDocs
There might be an error after the umount command to unmount the partition, ...because it is not mounted. Please post any errors you get here.

Edit: If you are not familiar with the command line and do not want to learn anything new try this http://talk.maemo.org/showpost.php?p=884265&postcount=4

That error is there if the partition is not mounted in the first place, but i wanted to be sure that it is not mounted, before trying to check the file system. Just go on with next line.

Please always post the complete error messages to give us a good chance to get what is going on.
Please try
Code:
sudo gainroot
fsck -r /dev/mmcblk0p1
If this still fails please give the full output of
Code:

Still not clear what the error for the file system is
Try
Code:
dosfsck -a -t -w -v /dev/mmcblk0p1

So i guess your file system is severely corrupt beyond a point of repair for fsck.

There are two, perhaps three, methods to go on from here:
1. If your data is still on your computer and easily to restore on the phone, you could formate the emmc freshly and recopy all your stuff to it.
Code:
mkfs.vfat -n MyDocs /dev/mmcblk0p1
2. You could try to get your data back from the device if you have no backup available with testdisk from recovery-tools package
Code:
apt-get install recovery-tools
testdisk /dev/mmcblk0
3. This a dangerous option: You could rewrite the file systems backup header to the partition. This could really do some magic, but could also destroy it beyond recovery if something goes weird.
Code:
dd if=/dev/mmcblk0p1 of=/dev/mmcblk0p1 bs=512 count=1 skip=6
You could find more on this slightly dangerous command here http://talk.maemo.org/showpost.php?p...8&postcount=31
