Verify failed after burning (L-EC Uncorrectable Error)

[XeRo]

Hello,

 

I've burned and verified successfully with a different iso using the DVD-R disc, but for some reason this iso failed to verify using the same disc type and drive. If can anyone could help by explaining what went wrong that would be greatly appreciated. Here is the log file:

You should generally avoid CMC as a rule.  However, if you've used them fine for a long enough period of time that they haven't given you reason to question them, the drive may have reached the end of its life.  Failures to Verify generally mean the burn wasn't done correctly.  And that generally, but not always, means it's the fault of the drive or the media.  Without using quality media, I can't say what the situation is in this case.  What you could try to see if it's just a problem with the ISO is try to find a CMC disc that did burn and verify, read it to an image, and then try burning that new read to another CMC disc.  If it fails again, then you know it's most likely not the ISO that's the problem in either case.  It's the CMC discs or your drive has reached the end of its life.

Thanks for replying, I had did what you suggested and the burn and verify worked successfully as expected. So that rules out the discs and my drive being dead. Which lead me to look at the filesize of the iso i was trying to burn. The Memorex DVD-R disc holds 4.7 GB and the iso that failed to verify is 4.37 GB according to my laptop. So I figured, the filesize is not the issue but I googled "dvd-r 4.7gb capacity" anyways and found a link that informed me that manufacturers use decimal "base 10" while operating systems use binary "base 2" so dvd-r disc really holds 4.3 GB. I could be wrong but I think this maybe why the disc failed, the iso might be too big. The iso that did succeed was much smaller; only 1.35 GB. Like I said before, it worked again when I created an image and burned it onto a new disc.

It's nothing to do with the size of the image... beyond a larger image obviously taking up more space on the disc and therefore a larger area over which an error could occur.

 

You've got an unreliable drive/media combo.

[dbminter]

Plus, a larger image file size that approaches the maximum space of the media means you're writing more data closer to the edge of the disc.  Another common place for errors to occur is when you're writing near the edge.  The smaller ISO could explain why it worked.
