hi ive recently bought a hacked 360 and a kreon drive. i had no problems backing up games untill this morning. i opened up xbc start ripping a game and it sticks on 3.39% for a few seconds then carrys on ripping REALLY slowly. every few minutes it says "block error recovered" ive tried ripping games that i have ripped perfectly before but it just says "Block error recovered" and takes ages
is there something wrong with my drive?

Try cleaning your Kreon's drive's laser with alcohol

Have you changed the master/slave jumper ? Mine's a bitch if it's not in master.

Sounds like it has trouble reading the original game. Does the game disc has scratches? If cleaning the laser doesn't work, do what I did and buy another kreon drive.
