Depends on the problem with the HDD.
If it's physical, you might need to replace the PCB and then try it out. If it's the software kind or a mistake that lead to data being erased, you could use softwares available out there to recover data. I use recover my files from http://www.recovermyfiles.com/ for such problems.
But there a hundreds of softwares and services available out there. Just google something up which is within your budget and closer to your area.
