Ошибка при получении информации ATA диска на C# ⇐ C#

[Anonymous]

Я создавал консольное приложение C++ для получения информации ATA диска, но получал код ошибки 1 в DeviceIoControl, поэтому попробовал его на C#.ATAFeaturesForm.cs

Я получил код ошибки 87, связанный с неверным параметром, я потратил на это около 2 недель, я оставил комментарии над DeviceIoControl. Вот в чем проблема, может кто-нибудь мне помочь!
Кто-нибудь знает, с помощью какого IOCTL я могу получить эти данные или причину ошибки в моем коде?
