Arch linux not booting after shutdown laptop once X freezes

Hi all!

Currently I have problems when I plug/unplug AC power adapter, X freezes, a black screen is presented with a white cursor blinking at the top left of the screen.
So I have shutdown my laptop by pressing the power button.

Now Arch linux does not boot and also I cannot access to emergency console.

See images attached.

Screenshot 2

I have peform following steps to try to solve this but without success:

1.- Using an Arch LiveCD I have accessed to console
2.- Mount lvm partitions and mount boot partition
3.- Perform arch-chroot on mounted directory
4.- Type in passwd root command in order to change root password
5.- exit arch-root
6.- unmount partitions previously mounted on step 2
7.- reboot

And it continues with the same error messages at boot:

Please, could anyone help me?

Thanks in advance.

There's a critical blk_update_request error on the 3rd screenshot (but the line is unreadably blurred)
=> what is the UUID (complare "lsblk -f", doesn't seem to be the root device) and check filesystem (which one?) and disk status w/ eg. grml (I'm not sure the arch iso ships smartctl)

Elaborate on the hardware (SSD or HDD, vendor, model, age - see the smatctl output) and filesystem

The output for lsblk -f command is below (/dev/sdc is an external hdd drive connected through USB to my laptop and this is where Arch Linux resides):

Screenshot #5 for lsblk -f command

Regarding the critical blk_update_request error on the 3rd screenshot, it is the same error message shown after getting LiveCD prompt and when doing a journalctl -xb. See below images:

Screenshot #6 - Error shown on LiveCD prompt
Screenshot #7 - Journalctl -xb output

I have passed a short test using smartctl and the result is passed. But I have observed drive contains some bad sectors.

Is there any way to check the drive or repair partition? Through LiveCD I have tried to perform and fsck -a and fsck -r /dev/sdc but it does not work.....

Massive. Red. Flag.
Post the output of smartctl.

Secure all the important data on the drive first (not the OS and not your porn collection, but family pictures, thesis drafts, … stuff that isn't currently copied elsewhere. Ok, and maybe the porn.)
