I've a WDC WD2000BB HHD with 200GB and my BIOS will not work with it. I flashed the latest BIOS-Update GA-6BXC-F4c, but nothing gets better

Here are some data:
Program: eSupport.com BIOS Agent Version 3.2

If it is possible to get more than the max HDD size of 128GB ?
I get the "Data Lifeguard Tools 11 für Windows" from Western Digital Internet-Site, but it will erase the data on the HDD. That was very unfortunately because on the HDD is more than 70GB mp3-files (I didn't wan't to lose them).
I can put the HDD in an external case and connect to my machine via USB, but it's too slowly. I wan't to have a great internal HDD.
Is anybody here who can help me?
Thanks
Markus
