hi guys, i have been burning ps2 backups using the same media for a while now (burned about 30) and now all of the sudden i get an "I/O Error" when trying to initialize burning and it also says "Power Calibration Error". i've looked at other threads to find a solution to this and most say that it's probably caused by cheap media, but since i've been using these for a long time that seems unlikely. does anyone know if this can be caused by a software update, or if my burner is just shot?? any suggestions will help! thanks!
