Преобразование кода HDD Serial # VB6 в код VB.NET

У меня есть классный фрагмент кода, взятый из проекта VC++, который получает полную информацию о жестком диске БЕЗ использования WMI (поскольку у WMI есть свои проблемы) Я прошу тех из вас, кто знаком с функциями API, попытаться преобразовать этот код VB6 в VB (или C#) .NET и помочь МНОГО людей, которые очень нуждаются в этом служебном классе. Я потратил много времени и обыскал всю сеть, чтобы найти способы узнать фактическую модель и серийный номер жесткого диска, и в конце концов нашел этот, если бы он был в .NET ... Вот код и извините за проблемы с форматированием, просто вставьте его в VB6 IDE:
