I have an LG5160D DVD WRITER THAT I USE TO BACKUP DVDS. Now all of a sudden it writes nothing but coasters. I am using one click and any dvd. Has anyone encountered this problem?
Could you make a screenshot of it properties via Nero InfoTool?
To verify drive operation, try creating and burning a DVD data disc. If the disc burns properly and all of the files can be read, then your burner is fine and you have a software problem. In which case, uninstalling and reinstalling all of the software used will likely solve the problem (one at a time so you will know which one actually failed). If the data disc also doesn’t work, then you likely have a burner, media, or burning software issue.
