I had my N900 device stuck with a "no files/folders" issue
and told to backup rootfs and optfs to emmc using BackupMenu
and then run the 'fsck' on all partitions command to repartition it
so errors will be fixed and emmc and SDcard should mount.

well, I did it .
BUT......
when I've run fcsk all partitions .....nothing happens !!
as i reboot i still got no access to device nor SD.

Am I missing something ? should i do anything else ?
