Removing an HPA/DCO

I apologize if I am posting in the wrong forum, if there is a better place to post please let me know. I am trying to write a program that will check for an HPA or DCO and then allow someone to able to remove it. I know that some of the ATA hard drive commands you would use are READ_NATIVE_MAX_ADDRESS and IDENTIFY_DEVICE for working with the HPA and of course the DCO has its own set, but I was hoping to find out how to use java to run those low level commands. I've never worked with java before, so any help would be very much appreciated.
