I did have some problems with rawdump in the past http://www.wiihacks.com/dumping-burn...ing-512kb.html

But now, after about 6 dumps, it stops after 379Mb and the speed halves about every 3 seconds. I'm trying everything not to use a wifi or usb dump to save on wear and tear on the dvd drive. Nothings changed from the earlier thread so I dont know what could have happened.
