Hi guys, I was trying to burn a iso file that requires to be burned with a dual layer burner. So i tried to burn it and at around 9% of burning completion, i get an error with imgburn, says I/O error, interpretation: check condition. I wasted 3 DL disks trying to burn this iso and then i tried to burn a different iso just to test and got the same problem. getting that error at around 9%. ive tried burning dvd's and cd's and they burn fine. I have an acer aspire 4810tz laptop and was wondering what the problem is? is it my burner or is it the media im using? btw im using memorex dl dvd's and they were working and burning fine last month but today for some reason when i tried to burn i get an error with imgburn. any help is appreciated! thanks!
