Saya jarang menggunakan cd di laptop saya, tetapi saya ingat memiliki masalah yang sama beberapa bulan yang lalu. Ketika saya meletakkan cd di drive DVD saya tidak ada yang terjadi. Itu menendang terakhir kali tanpa saya melakukan apa pun tetapi saya tidak tahu apa yang salah. Saya perlu membakar cd dengan k3b tetapi memberikan kesalahan "tidak ada perangkat optik yang ditemukan".
Sistem saya adalah Fedora 20 x86_64. Masalah: CD tidak bisa dipasang, ketika dimasukkan ke drive tidak ada yang terjadi.
Apa yang bisa saya lakukan untuk mengatasi masalah ini?
PEMBARUAN SAAT INI: Masalah: cd dan dvd tidak berfungsi sebagaimana mestinya, sejak berbaris mereka tidak stabil seperti pada "tidak pemasangan ketika dimasukkan", "pemasangan saat dimasukkan tetapi melepaskan secara acak" / "tidak memasang secara acak", ketika disconnet disk tidak terlihat ke sistem dan saya tidak bisa mengeluarkan disk.
Saya memasukkan film dvd ke drive kemarin, ia dipasang di / run / media / nama pengguna / MOUNTPOINT dan semuanya berfungsi, lalu setelah beberapa saat menghilang, tidak dipasang lagi dan saya tidak bisa mengeluarkan dvd dari drive. Beginilah sekarang, masih di drive, berikut adalah beberapa perintah yang berfungsi di drive seperti sekarang:

Perilaku dari drive dvd, disk, dan dvd sudah terpasang /run/media/username/MOUNTPOINT dan berfungsi, tetapi kemudian mereka dapat memutusnya kapan saja, dan ketika disconnect, mereka tidak muncul di mana pun dalam sistem, dan saya tidak dapat mengeluarkan disk.
Ketika saya menutup penutupnya, laptop diatur ke "tidur", saya melakukan ini 4 jam yang lalu, dan ketika saya mencabutnya satu jam yang lalu dvd di drive sudah terpasang /run/media/username/MOUNTPOINT. Beginilah sekarang:

Ini adalah output dari perintah cd-info: pastebin
Sepertinya semua yang Anda lakukan benar untuk mendiagnosis masalahnya. Dari saya mengerti itu driver cd yang buruk, perangkat keras yang buruk. Ketika Anda menyebutkan "Ini menendang terakhir kali tanpa saya melakukan apa-apa" maka itu berfungsi terakhir kali tetapi sekarang ini masalah perangkat keras. Entah itu me-mount drive, tetapi jika itu bekerja sekali dan tidak me-mount lagi, itu semua menyimpulkan kegagalan perangkat keras menurut saya.

wodimbisa jadi menyebalkan. Anda juga menjalankan GNOME? Apakah Nautilus tidak menampilkan drive DVD ketika Anda memasukkan DVD ke dalam drive?
@slm Saya menjalankan KDE, dua hari yang lalu saya memasukkan film dvd, itu muncul di Dolphin dan jika saya "df -h" itu dipasang di / var / run / media / nama pengguna / MOUNTPOINT, tetapi sudah tersimpan di drive karena dan sebagian besar waktu itu tidak ditemukan di mana pun dan tidak dipasang, juga saya tidak bisa mengeluarkannya dari drive. Pikirkan jika saya reboot itu terdeteksi. Saya tidak pernah punya masalah mengeluarkan disk lebih dari beberapa jam.

k3bada kemungkinank3btidak berjalan dengan hak akses yang cukup. Awalnya, Anda harus mencoba menjalankank3bsebagai root dan memverifikasi apakah CD diidentifikasi dengan benar.
