Info wanted on dumping UMD's..

Is it possible to do it with HEN? Does it ruin the UMD? How long does it normally take? How can I do it?Main reason I wanna dump my UMD's is because I don't wanna wait to download them, and i'm sick of the long loading times. I may have more questions based on replies.

Hypnos has a topic in the tutorial section about doing it.
