Take hard drive out of psr9000 and attach to regular pc using adapter! ... and transfer all styles and karaoke stuff onto hard drive! Adapter costs 6 dollars! Part number is:
LAPTOP HARD DRIVE ADAPTER IDC44F/IDC40M
Do a google search and you will come up with places to buy it!
This is poor man's way ... instead of getting the usb internal way(150 dollars)!
