Issue related to external HDD 500GB drive

I own a MY PASSPORT EXTERNAL HDD 500GB.

I have been facing an issue from last 1 day that my drive is powering up but it’s not working.

I have contacted WD for replacement process and is there any option to get my data recovery done before getting my 

drive replaced.

Please help me out with this and if I have to pay anything can you people provide me an idea about how much I have to 

pay for the data recovery.

You can try to recover your files using Recuva.
