如何在Windows上檢索磁盤標識符？這不要與卷標識符混淆;他們是兩回事。磁盤標識符是駐留在MBR中的4字節標識符（如果使用GPT，則爲16字節標識符）。如果運行diskpart並查詢磁盤的詳細信息，則爲標有「磁盤ID」的值。如何在Windows上獲取磁盤標識符？
我已經瀏覽了所有看起來相關的MSDN文檔，但我還沒有設法找到任何能夠做到這一點的東西;顯然這是可能的，但看到diskpart能夠從某處獲得該值。
我總是可以調用diskpart作爲最後的手段並解析它的輸出，但是我真的希望避免這樣做。有誰知道我怎樣才能以編程方式獲得這個號碼？
可以使用Win32_DiskDrive WMI類和Signature財產。

我希望避免WMI，因爲代碼太糟糕了，但看起來沒有選擇。謝謝。 – 2012-03-22 02:50:01
您應該可以使用WMI完成此任務。
你所尋求的數據可能是一個在Win32_DiskDrive類的DeviceID成員，否則你不得不嘗試:)
運行在命令行中輸入以下代碼給出了磁盤ID該系統上的設備的S：
wmic diskdrive get serialnumber
注意：如果外部驅動器，諸如USB閃盤是connecte到你的機器，它會在上面的命令的輸出中列出了。
假設您擁有管理員權限，您可以打開一個文件句柄到'\\。\ PhysicalDrive0'並直接讀取MBR。 – 2012-03-22 06:55:28
