Hard disk failure

I tried your suggestion but I don’t think it is showing me my WD devise at all.  There is one component called the “system” that I am not sure of but the capacity is listed as 199MB.  The other components are my HP_tools, my C drive and my recovery drive (which is tiny).  What can I do?  Can I take the hard drive apart and put it into any of those hard drive recovery units (I cannot remember the technical name at the moment)?  Thank you for your help.
