Additional Hard drive added to Alienware m17x r2, now crashing.

I added an additional toshiba hard drive to my laptop. Now when i try to install stuff on it, mid-way through my computer will freeze and crash. I got a replacement hard drive and still have the same issue so i believe it is a set-up problem.

It crashes whenever in use not just when installing things. I tried defragmentating the disk and crashed in the process.
