i recently connected my n900 to a cmputer which i think it had viruses ( a window machine of course) because after i connected it, MyDocs partion didnt showed up with a normal mass storage icon instead it had a normal file icon, after i removed it i didnt looked it up on file manager ( i was busy doing a certain work), and i took it to another pc which had an antivirus ( the massage of Norton came up but i didnt bother i just cancelled them), but when i selected mass storage only my MMC showed up and MyDocs partition didnt showed up, i unpluged it from a pc and went to file manager but only MMC was there and not myDocs, i rebooted the phone but the same problem cant find it on neither file manager nor on filebox on mmc can seen, i dont know whats is the problem, when i viewed on xterminal i can see myDocs directory but it contains nothing.
Can somebody help me to bring myDocs partition back with its data

So the partition is there but the file system is corrupt. It looks to me like a result of an unclean unmount. Try:

Code:

dosfsck /dev/mmcblk0p1

Another option is connect to a Windows PC and run checkdisk. I've read amazing stories on this forum of people with similar problems who fixed it by a simple checkdisk.

If fsck don't work, check that thread out http://talk.maemo.org/showthread.php?t=82049 and maybe you could get your data back.
Good lucky !

Install "TestDisk" - this does the above and more.
The usual virus will try to change the MBR, but "MyDocs" runs "ext2" that is fully journalled. Load the journal, and scan the entire filesystem.

Drop Windows - this does not know about the file system, it can easily destroy it.
If the MBR has been modified, loading the previous value is the only way forward You loose the last second or two... The typical error is that the file system tye is unknown. List the types - look for "ext2" - which should be used.
If you just get hold of the journal master block, TestDisk will restore your entire "MyDocs" - also the ._Trashes directory. Use your PC to learn aout Linux / Unix commands.
