USB 3.0 ハードディスク・ケースの相性問題

USB 3.0インターフェースのハードディスク・ケースが、認識したり しなかったり…。 Google検索しても、ケース自体や、ケーブルなど含めて相性問題がけっこうあるようだ。

ログにはエラーが記録されていて、接続時に「ERROR Transfer event for disabled endpoint or incorrect stream ring」が出力され、取り外し時に「Synchronize Cache(10) failed: Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK」が出力されている。

実際に利用中に、エラーを体感することはなかったが、ログにエラーが吐き出されているので要注意の製品。
