I FORMATED A SMALL PARTION ON MY HDLOADER HARDDRIVE AND FORMATED IT WITH USBADVANCE, THEN PUT ALL MY ELF FILES ON THE HDADVANCE PARTION AND LAUNCH ELF WAS ABLE TO READ THE PARTION AS A MASS STORAGE DRIVE, KINDA COOL MAKES IT REALLY EASY TO AD NEW HDLOADER FILES OR ANYTHING YOU MIGHT WANT ON YOUR PS2, THOGHT IT MIGHT BE USEFULL TO SOMEONE LET ME KNOW. cAUTION TO NEWBS DON'T FORMAT THE WHOLE DRIVE OR YOU WILL LOOSE ALL GAMES AND HDLOADER DATA. bEST IF SET UP ON A DIFFERENT DRIVE, THAT WAY YOU CAN DO IT ON THE FLY.
