It is fine to investigate errors to learn about it (but not to vent about it in a forum for help), but many questions you might have can be answered by either reading and understanding the problem or by looking it up. A great example is some of the supposed errors in this thread, the error itself explains why it occurs, e.g. "the operation requested is not supported by the hardware" when you were trying to defrag your drive. Continuing on that, there's no need for you to manually defrag or in any other way optimize your drives as Windows is perfectly capable of managing it automatically.
[USER=8382]@DR M[/USER] has mentioned it multiple times, but I'd like to additionally mention something about not using FRST or any similar tool without guidance. These tools are potentially dangerous if used incorrectly as they can cause irreparable damage, which is why you should only use them with guidance from an expert.
