Bad ac adapter

Hi there, I am new in this.

 My problem is that i bought a WD elements 500GB HDD.It worked fine half year,but now everytime i try to connect the power supply to the HD  it doesn’t works,  it just shuts down and hard doesn’t works. I think that ac adapter is bad. I have very important files in the hdd and don’t want to lose it.

Model no:ad6008
