I recently bought usb extreme and an CompUSA 160GB external USB 2.0 HDD and it's friggin awesome. I have "backed up" a buttload of ps2 games on it but have come across 1 game that wont boot named "Bully". The directions dont say how to delete unwanted games off the HDD. There is a format button on the screen but I have been afraid to try it thinking that instead of deleting the one game it will reformat the entire HDD. Who knows how to delete a single game only?
