It's becoming a pain in the ass

I did a clean install of kubuntu and today my computer hung, so I had to just switch it of. Now my secondary HDD can’t be mounted it gives the following error:

An error occurred while accessing ‘HDD2’, the system responded: The requested operation has failed: Error mounting /dev/sda2 at /media/aristarkos/HDD2: wrong fs type, bad option, bad superblock on /dev/sda2, missing codepage or helper program, or other error

I have no idea how to solve this, do any of you have a clue?

Thanks in advance.
