The physical size of the device is 122096381 blocks
Either the superblock or the partition table is likely to be corrupt!
Abort<y>? no

Backup contains a file system with errors, check forced.
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information
Backup: 223131/30531584 files (0.1% non-contiguous), 44383187/122096646 blocks

$ sudo mkdir /mnt/backup

$ sudo mount -t ext4 /dev/sda /mnt/backup
mount: wrong fs type, bad option, bad superblock on /dev/sda,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so
Looks familiar. And looking at dmesg | tail:

$ dmesg | tail
[359222.668707] EXT4-fs (sda): bad geometry: block count 122096646 exceeds size of device (122096381 blocks)
Also seen that before. I did some searching and thought that maybe using resize2fs (resize filesystem) was a command that could help. I asked if they thought this was correct and whether there was anything else I should try. They suggested I also try:

$ sudo mount -t ext4 -o ro /dev/sda /mnt/backup
Which failed the same way as the earlier mount attempt. Then I took a deep breath and resized the filesystem as he suggested:

$ sudo resize2fs /dev/sda 465G
resize2fs 1.41.14 (22-Dec-2010)
Resizing the filesystem on /dev/sda to 121896960 (4k) blocks.
The filesystem on /dev/sda is now 121896960 blocks long.
And after that, mounting my drive was successful and I can access all my data again!

Thank you all to have offered their advice and help throughout this ordeal. Its kind of a face palm moment when you realize that all this reading and researching and asking questions and worrying was solved by running a single, simple command-line application. But its bee n a learning experience!
Man! Thanks for all of this research and effort! I have been wondering around internet since last month as I had the same problem as yours, however, the root of my problem was different.

The drive that I had issues with comes from a WiFi router (D-link model DIR-685). It has a HDD bay to plug in a standard 2.5 SATA, since the beginig this router was very hard to configured to have it as a storage server, once it was working, few days later when I was uploading some files I noticed that the date was wrong (it was 2013 and the date was Dec 2012) so when I tried to change it in the router console, it didn't let me put anything higher that Dec 31 2012!!! I looked for any firmware upgrade but there was none, in the support page the model was not listed. After those issues came up I started having issues trying to access my data up to a point in which I was no longar able to even see the drive.

I'm writing all my description just in case someone else is having the same problem.
And thanks again everyone!!!
