What is your Windows version and Service Pack?
What is the issue you are having that you think updating the ATA driver will solve?
The FUJITSU MHY2160BH is a hard drive and the ATA drivers are for your motherboard so we need to know what that is so do this:

There will be some personal information (like System Name and User Name), and whatever appears to be private information to you, just delete it from the pasted information.
