What are next steps when fsck reports "could not be repaired after 3 attempts"? My Mac Book Pro 13.-" doesn´t get past the grey booting screen with the apple and the spinning wheel (The loading bar appears but when it´s done nothing happens) 

I have 220 GB in one single Partition (Macintosh HD) and there is all my work my music and the only copy of ALL MY PHOTOS. I´m so stupid I don´t have a backup of anything but know I have an external HD with 300GB space. I would like to repair my HDD but more important I need to save my files but I don´t know how to do it in Disk Utility Mode. I read there is a Diskwarrior but I don´t know how to install it without booting the mac. Please help!!!

When I start on Single User mode and enter /sbin/fsck -fs this appears

What are the next steps if fsck fails to repair a drive?
You can try this but please make sure you backup first: 

Boot to single-user mode, hold down the command (i.e. cloverleaf or Apple) and "s" keys as the system begins to boot.

To Debug, Repair, Force (and fix errors automatically)

/sbin/fsck_hfs -drfy /dev/disk0s2


To scan for bad blocks:

/sbin/fsck_hfs -S /dev/disk0s2


Assuming disk0s2 is the one you are looking to repair. (Usually the default "Macintosh HD" drive.)

This should get you back inside your OS.
