写个取硬盘号的注册程序,测试了IDE可以,但串口硬盘不行,能否给点思路,谢谢了

在网上找了一段,你看是不是你需要的:

希捷ST3 250G的串口硬盘,物理序列号可以读取:

Code
ManagementObjectSearcher searcher = new
ManagementObjectSearcher(
"SELECT * FROM Win32_DiskDrive");

foreach (ManagementObject wmi_HD in searcher.Get())
{
HardDrive hd
= new HardDrive();
try
{
hd.Model
= wmi_HD["Model"].ToString();
}
catch (Exception)
{
hd.Model
= "Unknown";
}
}

 

多块硬盘,可以只取固定硬盘,取的一块。
