Linux forum: Ext4 partition is not working

Basically a few days ago I was setting up a seperate partition for my brother to use, to download ubuntu 12.04 on using a Fedora 16 livecd of mine.

I free'd about 103GB of space off of my ext4 partition (sdb5)
which (should) have another 60GB of free space left in it. sdb5 is also the partition that holds my normal OS (ubuntu 11.10) that I login to every day, and most of my important files.

When I tried rebooting into ubuntu (have not installed the new OS) it booted into the initramfs prompt. This striked me as odd, and after a little while I found out that the filesystem size was larger than the device size.

some information:
[root@localhost liveuser]# e2fsck -yv /dev/sdb5
e2fsck 1.41.14 (22-Dec-2010)
The filesystem size (according to the superblock) is 64000000 blocks
The physical size of the device is 63999809 blocks
Either the superblock or the partition table is likely to be corrupt!
Abort? yes

I have no idea what to do now, and I'm honestly about to trash the partition all together; I was just hoping to save a few of my files from it but it doesn't look like I'll be able to. Any suggestions would be greatly appreciated.
