場合によっては、コンピュータを起動すると、ロゴ画面の後に_
(アンダースコア)が点滅し、コンピュータが起動しないことがあります。その後、正しく機能するためには、電源からプラグを抜いて再起動する必要がありました。それでは私のコンピュータに何が問題なのか教えてください。私の仕様は
Debian 7, 512 MB RAM 3 GHZ PENTIUM D PROCESSOR 256 MB GRAPHICS
答え1
これはDebianとは何の関係もありません。あなたが経験している問題は、オペレーティングシステムが起動する前に発生します。奇妙なことに、これは時々起こります。
1つの可能性は、ハードドライブにエラーが発生したことです。出力を確認してください
sudo smartctl -a /dev/sda
次の行が表示されます。
SMART overall-health self-assessment test result: PASSED
GRUBが取り付けられていない場合は、正しいデバイスと/dev/sda
交換してください。/dev/sda
以下をインストールする必要がありますsmartctl
。
sudo apt-get install smartmontools

そのため、ドライブからデータを読み取るのに問題があるようです。この問題が最近開始された場合、ドライブが破損している可能性があります。私はあなたをお勧めしますすばやくバックアップして新しいドライブを購入する。
ドライブを交換する前に、ケーブルの接続が正しいことを確認し(HDDケーブル)、他のケーブルを試してみてください。
