This may be completely obvious to everyone but me, but after struggling with it, I thought I would pass on my experience. For anyone who wants the solution without the story, just skip to the end to "What Worked:" After doing a successful burn of an image to a DVD using Nero Essentials, I had problems burning a simple non-image dvd. I solved this finally, mainly by not giving up. This is sort of the process I went through to find the right solution: I put a brand new dvd in my cd/dvd burner and checked how much space it had and it showed in Windows Explorer as having no available space even though it was brand new. I tried several others and all were listed as full. I found this annoying and tried to burn it anyway and got an error message with the number (052602) and the word Invalid, so it was probably the error "Parameter Value Invalid". I read in different forums that my burner might be dying, which I didn't really believe. I then read I should switch the SATA cable from the black connection to the red one, presumably because the red one has a greater capacity, which I did - Nada! I then uninstalled Nero Essentials and installed AShampoo. I tried a DVD-RW and had AShampoo reformat the disk. I set the burning speed down from 4 to 2. It then burned the DVD but the DVD failed the test. I tried using it anyway, and my computer hung up. I then had it reformat the DVD-RW again and had it burn one file type at a time, starting with .exe files, then Zip files, then a variety of non-standard files. All burned fine. What Worked: What I finally learned out of all this is that although creating folders is an option in the burning software, my burner didn't want anything in the folders. It would only burn empty folders. It didn't matter if the folders were "added" from my computer or if they were created and then the contents were "added" to the newly created folders. It simply didn't like folders. So, I zipped up the contents of the folders and burned them as zip files. Everything seemed to work that way. Is this normal for burners? Is there some step like Tree-Structure or something that is needed for folders? May you burn safely and successfully.
