Program seems great, however when I try and save a backup of a partion D on my LG liteon 16 speed DVD burner using Verbatum 16 speed DVD discs, it will not do it, says that function is not available. I have Nero burning software with INCD DVD burning and formating program installed. It burns just fine with every other program. Any help would be much appreciated. I sent email to Acronis tech support ,but no reply yet. Gary Moore. Also have latest update to program installed.
