I attached partitiontable.txt in attachments.

Code:

sudo gainroot
sfdisk -l > partitiontable.new

Later format your partition as root

Code:

mkfs.ext3 -m 1 -L home /dev/mmcblk0p2

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

Device Boot Start End #cyls #blocks Id System
/dev/mmcblk0p1 1 884864 884864 28315648 c W95 FAT32 (LBA)
/dev/mmcblk0p2 884865 950400 65536 2097152 83 Linux
/dev/mmcblk0p3 950401 974976 24576 786432 82 Linux swap / Solaris
/dev/mmcblk0p4 0 - 0 0 0 Empty

In your first post you write about a custom partitioning of MyDocs and optfs-partitions, but your partition table does not show any signs of customizationThis is still the partition setup Nokia applied. Do you just need a fresh file system for /dev/mmcblk0p2 or do you need the partitions' sizes to be altered?
Please as English is not my first language be as clear as possible, how i could assist you.

What made me mad that i can see 27GB MyDocs.. and 5GB Applicable memory not corrupted!

According to the 'partitionstable.new' you posted, your N900 have the default setup of 28GB MyDocs, 2GB /home and the 750 MB swap! May be Nokia care did reset it this way, i do not know!
There are a couple of commands to take a look at the health of your device. Please attach the resulting file 'test.txt' of this test here.

Code:

df -h > test.txt
mount >> test.txt
lshal | grep volume >> test.txt

Well there are good news ...and there are bad news!
Your EMMC is working just fine: lshal shows that hal is picking up all of the partitions. Your MyDocs partition of 27GB is 50% free and is mounted without errors.
But your rootfs is almost full (96%), partly because optfs, aka. /dev/mmcblk0p2, is not available.

My advice would be:
1. Make a backup of all possible items in the in-built Backup application, especially the application list.
2. Format the partition /dev/mmcblk0p2 with

Code:

sudo gainroot
mkfs.ext3 -L optfs -m1 /dev/mmcblk0p2

3. Flash the firmware to make it use your freshly formatted optfs-partition according to this wiki-article http://wiki.maemo.org/Updating_the_tablet_firmware . Only flash the fiasco image, i would suggest to use a Debian- or Ubuntu-based Linux-Live-CD, which you might also use to enlarge your optfs to the desired 5 GB later.
4. Use the Backup application to rebuilt your applications.
5. Now install backupmenu to the N900 from the application manager of your choice
5. Resize optfs (Enlarge) to 5GB and MyDocs (Shrink) to 24 GB according to this wiki-article http://wiki.maemo.org/Repartitioning_the_flash . Do not use one of the Manual Solutions #1 to #7. Although they still may work, they are fairly outdated. Either use the part 'Using gparted' at the beginning of that side or use Solution#8The GUI-Solution at the end of the side.

And: Do not hesitate to ask for more information for any of the steps or if errors occur again!
