Check the mechanical components of your HDD.
Let’s say that all of the components looked good inside of the HDD and that you don’t your Raid Server Data Recovery Software came up empty. Maybe it is time to address the mechanical components of your hard drive. Sometimes these small components will get all jammed up and stop working and they won’t show any easy way to be fixed. What you can do sounds bizarre but actually works. Hold your HDD a few inches above a hard surface and then let it fall onto its metal chassis. Try booting up the hard drive again and seeing if it is still jammed. Sometimes you might need to repeat the process a few times before it actually works.
