Internal Hard Drive not detected while installing Ubuntu 14.04

I'm trying to install Ubuntu 14.04 on a Dell Inspiron 3420 laptop. The problem is my 500GB hard drive is not detected during installation. I also tried gparted and the Disks application, but the hard drive is not detected in either of them. An input output error is shown.

I've checked similar questions but none of them have helped.

Feel free to ask, if further information is needed.

Any suggestions are appreciated.
