Liteon 411 problem

My drive stopped burn CDR-s. It can only write on DVD+R. It can read everything. When I try to resolve this I overclock it to 811 with EEPROM utility and I’m update the firmware, now it can write 8x but only on DVD+R, still can’t write on CDR. What is the problem?

same problem here on my 811
i tried everything
1 cleaning optical lens
2 different firmware
3 replaced to other computer
4 smashed it [carefull :slight_smile: ]

didn’t work i think its old age i have the grandfather of the Liteon drives :sad:
