You could try cleaning the drive with a cleaning disc and maybe attempt an 8x burn.
Other than that though, buy some better CD-R's! If your drive keeps erroring out during the burn, obviously it has a problem with them.
Personally, I wouldn't bother with anything other than Taiyo Yuden CDs.
Think that's not the problem Lightning! Just burned a DVD on the same drive, NP...
Just burned 2 cd's (same brand (Nashuatec)) with only 1 song on it with Express Burn, no problem...
The drive is working 200% alright, the same disc with another program does work alright...
The DVD part of ImgBurn does work alright...
& It used 2 work fine on this machine, these discs, this drive, never needed MadFlac before on this machine, meaby something wrong with ImgBurn 2.5.x.x???
