Saya bertanya-tanya apakah hasil SMART selftest ini menunjukkan kegagalan drive, ini adalah satu-satunya drive yang muncul dengan 'selesai: baca kegagalan' dalam hasil.

Drive belum menunjukkan tanda-tanda kegagalan, selain dari output dari selftest SMART itu. Ini adalah output dari drive yang berbeda di sistem yang sama yang saat ini menjalankan SMART selftest

dan memposting bagian berlabelSMART Attributes Data Structure
yang berisi penghitung mentah. Khususnya yang pertama di sana adalahRaw_Read_Error_Rate
yang merupakan indikator "bad drive" terbaik (dan mungkin akan! 0 dalam kasus Anda).
