PS2 USB Hard Disk Connection

I try to make a connection from USB hard disk to my PS2 Slim 70004 using USBAdvance.

The first step is to make bootable CD that run on PS2. I can do this successfully.

The next step copying PS2 DVD game to my USB Hard disk. So far is OK.

After that attach the USB Hard disk to USB port on PS2. Run the PS2 using CD bootable i made befor.

Splash screen show up and then i can see game title that I copy to my USB hard disk. Then I choose one of the game and click Start. Showing Loading … Title Menu…. and stop !!!!. I Still can not run the PS2 game from USB hard disk 🙁

I don’t know why, and still searching how to make connection between PS2 and USB Hard disk
