此IOCTL 使用IOCTL_DISK_GET_DRIVE_GEOMETRY获取DISK_GEOMETRY结构,使用IOCTL_DISK_GET_LENGTH_INFO获取GET_LENGTH_INFORMATION结构。 这两个 IOCTL 都支持在 disk.sys 级别使用。 要求 展开表 要求值 Headerntdddisk.h (包括 Ntdddisk.h) 反馈 此页面是否有帮助?
IOCTL_DISK_GET_DRIVE_GEOMETRY已被IOCTL_DISK_GET_DRIVE_GEOMETRY_EX取代,它會擷取其他資訊。 若要執行這項作業,請使用下列參數呼叫DeviceIoControl函式。 C++ BOOLDeviceIoControl( (HANDLE) hDevice,// handle to deviceIOCTL_DISK_GET_DRIVE_GEOMETRY,// dwIoControlCodeNULL,// lpInBuffer0,// nInBufferSize...

你要想获取U盘的真实容量，建议你用IOCTL_DISK_GET_DRIVE_GEOMETRY_EX指令，给你个小例子。BOOL GetDriveGeometryEX(LPWSTR wszPath, DISK_GEOMETRY_EX *pdg){ HANDLE hDevice = INVALID_HANDLE_VALUE; // handle to the drive to be examined BOOL bResult = FALSE; // results flag...
