I have just recently lost a hard drive to the RAW format and knoppix is able to read the disc with no errors compared to windows. I have been able to burn backup dvds with my sony dru 710a wich is capable of 16x, but they have only been burning at 1x. I am using the k3b software that comes with knoppix v 3.9 but have found no way of increasing the speed, although it starts the burn process saying it will burn at 8.2x, but for sure only burns at 1x. I am using growisof within k3b to burn the dvd. I have also noticed that my temp file size is only 189 megs, any way to increase this?. my cpu specs are a P4,256 RAM, cd-rw and dvd-rw ,plus a 20 gig, 60 gig, and 200 gig hard drive.
