Saya memiliki 300G Western Digital Raptor, baru-baru ini menunjukkan UNC SMART, bertanya-tanya siapa pun yang memiliki pengalaman tahu haruskah saya menggantinya dan mendapatkan formulir garansi WD?

Lakukan penggantian jika Anda bisa.

Di sisi lain ini adalah 'hanya' kesalahan baca yang tidak terlalu buruk. Jika Anda menulis ke sektor itu, maka Anda hanya dapat yakin jika memiliki cacat.

Saya akan menjalankan utilitas vendor untuk memeriksa (mereka juga menjalankan tes pintar) jika memiliki masalah. Mereka biasanya membuat cd bootable tersedia.

Anda dapat dan harus menjalankan tes mandiri yang dapat Anda lakukan dari linux dengan menerbitkan

smartctl -t long /dev/your-device

tunggu beberapa jam (ini akan menunjukkan perkiraan). Kemudian periksa kembali dengan

smartctl -a /dev/your-device

Jika dikatakan Completed without errorsAnda baik-baik saja. Jika tidak gunakan utilitas vendor untuk memeriksa drive.

Kesalahan baca dapat disebabkan oleh sesuatu yang sederhana seperti kehilangan daya selama operasi penulisan. Sendiri, mereka tidak menyarankan masalah perangkat keras dengan drive.
