Anyway using a LG drive to dump a Wii disc takes 50 hours or so... iirc.
The best way to dump your discs is to do it from your Wii, indeed.
Here's my method, it is safe and didn't brick my Wii. If it does brick yours then you're really, really unlucky.
You use the Twilight hack (you need Zelda Twilight Princess Wii) to install the Homebrew channel. This method
won't work if your firmware is version 4.0 or higher (mine is 3.3e, phew!).
Then you need to install a custom IOS (I used tona's one), and you can use the Wii Disc dumper.
The dumper can dump the disc to a SD card or an USB flash drive.
