clarify:
His disk drive does not work at all? how do you plan to back up the ISOs for game play?
If you can get your hands on a softmodded wii with a working disk drive, you can use a usb loader to backup games to play off of the hard drive, if not you'll have to buy one of these and rip them from your computer. You could also download the ISOs off the interwebz however I can't post useful links as it's against the TOS
Hitachi LG GDR-8161b (IDE)
Hitachi LG GDR-8162b (IDE)
Hitachi LG GDR-8163b (IDE)
Hitachi LG GDR-8164b (IDE)
Hitachi LG GDR-H10NBLK (SATA)
edit: OH I see what you mean, you're trying to use an external DVD drive to rip the game via your Wii. no, that's not possible. buy one of those LG drives and use your computer if you want to do that.
