If you've upgraded to Nero 6 in the last few days, you best take a look at this story over at CD Freaks which warns about a bug which can potentially wipe your HDD. Let's hope Ahead address it soon with a patch.
An Chang used our news submit to tell us that the German online magazine PCwelt.de reports that Nero 6 contains a 'bug' that could delete your entire harddrive. The bug is introduced with the Nero 6 Recode project. Bug might even not be the correct word for it, it seems more that Ahead forgot to limit the feature to empty the destination folder for temporarily files.More information @ CD Freaks
If this destination directory is set to the root of a disc (e.g C : ) and if the question: "Destination folder is not empty, do you wish to clear it" is answered with yes, all files will be deleted.
