Nero Could Not Perform the Start of Disc-At-Once

CD burning issues can spring from many variables. Finding the root of the issue can be tricky but it is necessary to successfully burn your disc. The variables come from the fact that are so many CD burner drives on the market today and an equally high variety of burning programs and writable discs.

1. Possible Cause 1: Disc Media

   • If you're having trouble writing in Disc-At-Once mode, the first thing you should check is your media. If you purchased cheap or low-quality discs, you may receive an error. In this case, you'll want to either try burning in Track-At-Once mode instead or purchase higher-quality writable discs. Find a high-quality brand of media that works for your system and stick with it in the future.

   Possible Cause 2: Diry Lens

   • If you're having trouble writing a Disc-At-Once disc, the cause may be a dirty CD writer lens. If this is the case, you should clean it with cotton swabs and rubbing alcohol. If this sounds too risky for you, use a CD laser lens cleaning CD instead. Always follow the directions closely for the cleaning CD.

   Possible Cause 3: Failing Drive

   • If you start receiving burn errors, your burning drive may be at the end of its useful life. In this case, you'll need to replace your burner. You may be tempted to think about repair as an option, but keep in mind that a new drive will be both faster and more reliable, making repairing your old burner a less attractive option.

   Possible Cause 4: DAO writing mode in conjunction with old drive

   • If you are receiving an error when trying to write a disc in Disc-At-Once mode, you may want to try writing in Track-At-Once mode instead. If you are using an older burning drive, it may not be able to write in Disc-At-Once mode.
