Ubuntu SSDが破損しているか/死にかけているかどうかを確認するにはどうすればよいですか？

昨夜、Ubuntu環境が非常に遅いように見えたため再起動したとき、警告画面に数行のテキストが表示されたままになりました（radeon Invalid ROM contentsについての何かはありません）。私はそれを何も考えず、愚かにも再起動しましたが、この長い画面に取って代わりました：

[ 160.053495] rc.loal[1933]: systemctl start teamviewerd.service
[ 182.741532] sd 6:0:0:0: timing out command, waited 180s
[ 182.741559] blk_update_request: I/O error, dev sdd, sector 0
[ 182.741575] Buffer I/O error on dev sdd, logical block 0, async page read
[ 360.134840] INFO: task systemd:3622 blocked for more than 120 seconds.
[ 360.134871]       Tainted: G      OE   4.4.0-116-generic #140-Ubuntu
[ 360.134898] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message

[ 504.125921] NMI watchdog: BUG: soft lockup - CPU#1 tuck for 22s! [systemd:1]
... More (but I am tired of transposing from picture)

セットアップ：

  • AMD R9 390グラフィックスカード（最初の段落のradeon？）
  • 2 SSD（WindowsおよびUbuntu）
  • 1台のHDD（2つに分割）

これらのメッセージのいくつかは、Ubuntu SSDが破損しているか、死に近づいているかどうかを調べ始めるように促しました。たとえば、私のファイル監視（開発者）は通常よりも苦労しているようで、プロジェクトファイルを開くのに私が覚えているよりも時間がかかりました。

オンラインの推奨事項からsmartmontoolsをインストールし、次を実行しました。

Sudo smartctl -H /dev/sda
Sudo smartctl -a /dev/sda
Sudo smartctl -t short /dev/sda
Sudo smartctl -l selftest /dev/sda

これは、前述のテストの出力でした Pastebin 。残念ながら、私はハードウェアの男ではなく、ここからどこへ行くべきか手がかりがありません。いずれかのテストの出力はドライブの故障を示唆していますか？

これが解決されるまで、Windowsでの開発（行き詰まり）が発生するため、これに関するヘルプは大歓迎です。 Ubuntuを起動することはできなくなりましたが、GRUBメニューからWindowsを選択しても問題なく動作します。 Ubuntuを安全に起動し、必要な小さなファイルをバックアップすることができたので、フォーマットが役立つ場合は間違いなく可能です（そして、ブートマネージャーを台無しにしません）。

Ubuntuインストールドライブを挿入し、ディスクから起動しようとしましたが、同じことが起こりました。 CDからブートされたshiftをタップしているときに別の再起動を行うため、「Press any key button」を見逃したに違いありません。

再起動後（CDから起動せずに）の初期出力は次のとおりです。

radeon 000:01;00.0: Invalid ROM contents

...eventually the screen went totally black, fixed by tapping the power button

Sudo parted -ls 
Sudo lsblk -f 
Sudo lsblk -m

GPUを取り出してUbuntu SSDで起動すると正常に動作しました。さらに奇妙なことに、GPUを元に戻す（PCを徹底的にクリーニングした後）ことで、Ubuntuを起動できます。

/dev/sdb（Ubuntu SSD）でsmartctlツールを実行し、この出力を受け取りました（ Pastebin ）：

testingと chat forum での議論の後、Ubuntuはコンピューターで再び動作します。

  • Ubuntu SSDはsmartmontoolsテストに合格しました

  • Radeonグラフィックカードのプラグを抜き、クリーニングして、再度差し込みました。おそらく、電気接続が不良だったため、プラグを抜いて再プラグすると問題が解決しました。
