私は最近、ストレージ用に新しいSATA 1TB Seagate Barracudaハードドライブをインストールしました。最近ドライブから「読み取る」まで1〜2分、運が良ければ数十秒ほど遅れる問題が発生しました。メディアを視聴すると、プログラムが中断され、そのlsディレクトリでの実行が遅れ、ゲームプレイが中断されます。
問題（SATA接続の失敗/カーネルの問題）を診断するにはどうすればよいですか？最近、間違ったシャットダウンのためにいくつかのディレクトリが破損した後、ドライブでe2fsckを実行しました。一部のユーザーは、ドライブの状態を確認するためにSMARTで起動することをお勧めします。私はDebianストレッチを使います。
uname -a
Linux vera 4.9.0-6-amd64 #1 SMP Debian 4.9.82-1+deb9u3 (2018-03-02) x86_64 GNU/Linux
だから/var/log/messagesを見て、これを見つけました。 SATA接続に欠陥があるようで、カーネルが接続を開始しようとしています。私は正しいですか？
