Saya memiliki drive berusia setahun yang memberi saya masalah. Menyalin data gagal setelah sekitar 8-10GB transfer. Secara spontan berubah menjadi 'hanya baca'. Ini diformat dengan benar ext4, saya pemiliknya. Pencarian online, sepertinya ini adalah gejala dari drive yang gagal.
Bagaimana cara mengkonfirmasi ini, karena tes SMART menunjukkan sebaliknya?
Saya melakukan yang jelas seperti memeriksa Disk Utility, dan menjalankan tes SMART yang diperluas. Semua hasil dari Disk Utility kembali sempurna. Tingkat kesalahan baca dan sektor yang dialokasikan kembali menunjukkan nol.
Saya menduga disk ini buruk dan SMART tidak mendeteksi, meskipun saya tidak mengerti mengapa. Saya ingin mengkonfirmasi apa masalahnya.
Saya tidak memiliki masalah dengan disk lain di mesin.

Terakhir tetapi tidak kalah pentingnya adalah screengrab baca / tulis, ini baru. Dulu tetap cukup konsisten selama durasi tes.
EDIT- Ketika saya menghidupkan pagi ini drive telah berubah dari / dev / sda ke / dev / sdc, aneh. Saya yakin itu belum terjadi sebelumnya dan saya yakin itu / dev / sda. Saya menukar kabel SATA dengan kabel yang bagus dan melihat kegagalan yang sama sekitar 10GB transfer. Saya belum mengubah port SATA, saya akan coba yang berikutnya. (Edit # 2, itu adalah port SATA, mengubahnya memperbaiki masalah. Memberi tanda ini terlalu lokal.)

sudo smartctl -a /dev/sdaJawaban:
Tes SMART "terisolasi", yaitu sekali
smartctlmemerintahkan drive untuk melakukan tes, drive menangani semuanya secara internal dan kemudian melaporkan kembali. Jadi ini mungkin tidak mengungkapkan masalah antara drive / controller dan motherboard Anda.smartctl -t long; tercepat dalam mode captive-C(lepaskan semua partisi!), dan ketika selesai, periksa status / kesalahan dengan-l(tes akan dibatalkan segera setelah kesalahan terdeteksi)Akhirnya, jika semua disk Anda baik-baik saja, ini mungkin merupakan bug aneh dengan pengontrol cache-tulis drive. Cadangkan data dan RMA sesegera mungkin.
(memposting pertanyaan dalam komentar dan saya akan memperbarui jawabannya. Semoga beruntung!)
