Mã này làm cho ba nỗ lực thu thập số serial:
- Sử dụng
IOCTL_STORAGE_QUERY_PROPERTY.
- Sử dụng
SMART_RCV_DRIVE_DATA.
- Sử dụng
IOCTL_SCSI_PASS_THROUGH.
Mã này làm việc cho tôi trên Windows 64-bit:

EDIT - Tôi đã thay đổi phương pháp chính để hiển thị kết quả của mỗi lần so sánh. Điều này hy vọng sẽ minh họa cách nhấn và bỏ lỡ những kỹ thuật này có thể được.
Một số thông tin khác có thể có liên quan - là hai hệ điều hành trên cùng một máy vật lý (tức là khởi động kép) hoặc các máy riêng biệt? Là một máy ảo? Bất cứ điều gì đáng chú ý về các đĩa, ví dụ: (RAID, v.v.)? –
Cả hai hệ điều hành đều trên cùng một máy vật lý. Không có máy ảo nào được sử dụng. Không có gì đặc biệt về ổ cứng của tôi, một ổ cứng ATA MAXTOR 160 GB điển hình. – TheAgent
Xin chào một lần nữa. Có lẽ EnumDisk1 cũng không nhận được số sê-ri trên Vista 64? –
