Code:

is the command to write the copy of the superblock back on the device
Code:
fsck -af /dev/mmcblk0p1
checks the filesystem afterwards. It might be necessary to apply some more force to the fsck command that would be
Code:
fsck -r /dev/mmcblk0p1
After you receive no more errors from fsck, you could mount the partition
Code:
mount /dev/mmcblk0p1 /home/user/MyDocs
This will be the final moment of truth, if all went well.
my n900, it not accept fsck... wat can i do now?

It really is difficult to pick up, what you are trying to achieve, from those one liners you are posting.
Please try to do what jedi asked and also describe the error you were facing first.

Yes it does.
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
Code:
sudo gainroot
fsck -af /dev/mmcblk0p1
If no errors occur, try to mount it
Code:
mount /dev/mmcblk0p1 /home/user/MyDocs
every time i try this, it works but when i reboot, i have to do it all over again. thanx by the way.

Don't reboot:D
Well the error must be happening while closing some applications or during shutdown.
Do you use file sharing on the N900, which is reported to sometimes corrupt the file system, or do you enable mass storage mode, while charging it via USB connected to a PC?

cant do anything because even with the temporary fix the memory still says corrupted. N900 folder appears in file manager but it is usless because i cant format or save anything to it.

First backup everything valuable on the partition to some external media, like external microSD or your PC.
And then apply a fresh file system to it with
Code:
sudo gainroot
umount /dev/mmcblk0p1
mkfs.vfat /dev/mmcblk0p1
mount /dev/mmcblk0p1 /home/user/MyDocs

One other semi-random thought... the only time I've had serious microSD card corruption was when I was first playing with kernel-power and experimented with the "starving" settings.

They appeared to work fine for most normal phone use and I was on the verge of replacing my microSD when I thought to check "what have I done recently?". Returning to the "ideal" voltages solved the problem and I haven't had any problems since - so, if you're doing any major undervolting, try changing that before assuming your SD card or filesystem is shot.
