親戚がSeagate 2TBの外付けハードドライブを見てみるように言い、以前は動作していましたが、今は動作しませんでした。lsusb。下に表示されるものを除き、デスクトップにポップアップしました。
約10分後に使用し、ついにls \dev | grep sd/dev/sdcとして表示されることを確認してみようとしましたが、fdisk -l記載されていませんでした。私はGPTテーブルかもしれないと思い、GPartedで開いていましたが、ロードに時間がかかり、lsblkどこで入手できるかを調べました。
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 111.8G 0 disk

└─sdb1 8:17 0 1.8T 0 part
sdc 8:32 0 128P 0 disk

今、私の親戚が人間に知られている最大のドライブを所有しているか、本当に奇妙なことが起こっています。後者と仮定すると、この問題を解決する方法はありますか？
いくつかの追加の注意：GPartedを使用してドライブを再度開こうとしましたが、今回はドライブがロードされるのを待っていました。また、明らかにパーティションが検出されておらず、親戚にはパーティション内のデータについて何もできないと言い、彼らはとにかく関係なくドライブを再利用できるようにしたいと言いました。

あなたの結果によると、smartctl問題は物理ストレージ逆に、ドライブに障害が発生した場合、サイズを正しく報告することもできないという事実（「ファームウェアに書き込む」必要がある）は、チェーン内の特定の時点でコントローラ電子機器にエラーが発生したことを意味します。
ほとんどの外付けUSBドライブは基本的ですが、常に高度なSMARTサポートではありません。シーゲイトドライブは、基本的な予想サポートさえ提供していないことが知られているので、SMARTエラーがコントローラの故障によって引き起こされると確信することは困難です。ただし、不正確に報告されたサイズは、実際にこれが発生していることを示しています。
「オールインワン」外付けドライブの場合は、物理ハードドライブを取り外して別のUSB-HDアダプタに接続してデータを回復できます。 （オンボードドライバの電子機器ではなくUSBインタフェースの電子機器に障害がある場合に発生します。）これが機能せず、同様のエラーが発生した場合は、データをリカバリラボに送信してデータをリカバリできます。これはしばしば非常に高価で、貴重な家族の写真や貴重なビットコイン財布などのものがある場合にのみ価値があります。
