after many power cuts and restarts, i'm unable to mount home partation any more,
i tryed to boot from the live image and mount the partation but get the following error:
i tryed to use fsck to check the partation file system and i got :
gparted:

now i intended to format the partation any way but i need 3 text files stored on it so i desprite need to recover the partation
i tryed to boot from the live image and mount the partation but get the following error:

In some cases useful info is found in syslog - try
