Error running Nero in multi-session mode

Asked By 0 points N/A Posted on -

Hi. I am using Nero for burning important photos and documents.

But while burning some files under multi-session, I got this error

Nero Express

The disc you have inserted is not empty, but the writing mode of your compilation is 'Start multisession' or 'No multisession'. This will cause the information already on the disc to be inaccessible via Windows Explorer.

Should Nero proceed with writing to this disc?"

I am running this on my Windows XP computer. What could be the problem behind it?

Please help me resolve it.

Error running Nero in multi-session mode


That error is occurring probably because you burned the first and subsequent sets of data using with the use of the 'multisession' option without selecting 'finalise cd' option. Although Windows Explorer may show the last track of a multisession CD in a normal burning process, the Nero burning  studio will automatically install a program that is known as  multi-mounter, and that is especially if you are using Nero 5.

To be able to use the multi-mounter application, you will need to do the following:

  • First you will need to load the CD
  • And then you will need to right-click on the CD drive in Windows Explorer
  • And then you will select Properties and then select the Volumes tab.

You should be able to see all of the tracks that are on the CD, and then you will just choose the track that you want and then click OK.

Error running Nero in multi-session mode


If you are burning your files under multisession then you are creating a multisession disc. A multisession disc allows you to burn data to the same disc in more than one writing session. This means you can eject the disc from the optical drive and put it back in later and write more files.

If your disc still has space after a writing session, you can burn more files at a later date using a multisession. Multisession discs are not often compatible with CD and DVD players. This is because a multisession disc is formatted as a data disk optimal for use on a PC or Macintosh. If you select multisession, you may encounter problems playing back the media in some drives.

Multisession should only be used when backing up data to a media and you wish to add more files later. For everything else, you should refrain from using multisession. I also encounter a somewhat similar problem before when I was also burning a multisession disc. Though in my case, I didn’t receive an error message. The problem came after the data was burned.

The disc was pretty much fine and accessible before my last burning session but after the last session, the entire disc became corrupted. The disc is no longer readable. So, in your case, if you don’t want to corrupt the disc you are using, in that dialog select “No” to abort the operation. That burning session will make your previous data inaccessible.
