Just like with the BIOS on your motherboard often times the manufacturer will find problems with the product after it has already begun shipping. They will apply the fixed BIOS to future shipping models and also post the updated BIOS to the web for us to download. You will need to know the model number of your drive before you can do this. Just like with BIOS updates, if it's not broke don't fix it! For firmware updates you will have to visit the manufacturers website and lookup your drives model number in their support sections.
