修复3个不能被Windows10认识的外接硬盘
昨天3个外接硬盘忽然不能被Windows10认识，插到电脑USB上，可以听到硬盘转动，但电脑上没有新装上外接硬盘的预告声。用Bitwar Data Recovery 和EaseUS Data Recovery软件都不能认出硬盘。因为有太多东西在硬盘上，着急了，急忙到gemini去问。Ai不是万能。它没有给出实质性的答案。
但是从YouTube找出了解决的方法，

5. Click yes, you will get:
6. Type "msdt -id DeviceDiagnostic", then hit return:
7. You will get:
8. Click Advanced, you will get this screen, set "Apply repairs automatically" , click next:

10. When the moving bar stops, you get:
11. Click on "I don't see my device listed", you get:
12. When finished, you get (I tried several times, sometimes this did not appear, but item 13 appears):
