[SOLVED] Can't mount /dev/sdax because of buggard superblock

I got an old laptop with a busted battery. This battery kinda gives out sometimes - as it did in this case - and now I can't get into my home directory.

As title says can't mount /dev/sda4 when booting in a live-usb. I am getting the following error:

 mount: /mnt: can't read superblock of dev/sda4 

I knew there was some kind of problem because I couldn't get far past grub on during the boot, and considering my /home is in its own partition I figured that it wasn't the problem. I was going to backup the files on the home partition that missed last night's backup and then reinstall on the root partition. Last but not least I wanted by pakbak directory so I could reinstall all my pacman stuff. Was gonna be clean and simple but yea, never that way is it?

I did some digging, and I ran the following commands already:

# mke2fs -n /dev/sda4 

and used that output to run:

 # fsck -b 32768 /dev/sda4 

however after reading the journal logs or whatever, it asked me to forice rewrite, I said yes of course... and nothing. just leaves me for hours today, can't give any new commands or nothing.

Am I doing something wrong?
I use ext4 with gpt. Up to date arch, march's ISO for the flash-drive live-cd.
I can sorta Arch-Chroot in the root partition, I recovered a txt file of my pacman stuff. It's just that home partition... the one I care about. There are only a few files that missed the back-up, but it's finals week for me and I kinda need that stuff. Any help much appreciated.

[SOLVED]

I got it to somehow work by just using another block sector. Thank you trial and error. Hopefull some google search down the line someone finds this and it helps them.
