[mz3bo]

Hi, I am using Alcohol 120% and Nero 6.0 with my Lg 4040 multi drive but when the drive finish reading the whole cd, it says It cannot continue because there is error due to Unreadable DATA. The DVD is flawless and ive been burning tons of PS2 game until today...

someone knows what<s wrong, I didn't check the box that mention Ignore read errors in alcohol 120%, should I do it ??

Thanks
