Unable to write more data to DVD+RW

I am having trouble adding data to a DVD+RW (Memorex) after adding data to the disc. After writing some data (about 100MB) to the disc (that can hold up to 4.7GB) I am unable to add anymore data to the disc. The “properties” of the disc tells me that the disc is full. Does anyone have any ideas? :confused: I have a HP notebook that using “Sonic”. Thanks in advance for any help.

Does Sonic support multisession discs? The reason you can’t add more to the disc is because you’ve finalized the session.

I did not press the finalize button, I was sure not to do that. Should I do something else? Thanks

Copy the content back, FULL FORMAT, then burn it again.
