Проблема с оптическим приводом(ноутбук)

[Alexz]

Через какое-то время в убунте отключается оптический привод. К примеру, вставляю диск,он автоматом монтируется в каталог /media/cdrom0, запускаю с него установку программы, идет установка и через какое-то время мне выдает окно "Вставьте CD-диск...". Смотрю в /media/cdrom0/ там пусто. Также и с другими дисками Причем диск крутится. На кнопку извлечения не реагирует.  eject -r, umount не помогают. В чем может быть причина? Как это исправить?
Вот что выдает lshw до его "отключения"

В последней строчке  configuration: в конце стоит status=open. Это получается он открыт что ли?
Ноутбук Asus M50Vc, Ubuntu 9.04, ядро 2.6.28-13.

Вывод dmesg ещё неплохо бы посмотреть на предмет ругани, связанной с приводом, буде таковая там имеется.

[alecsartania]

А во тесли  LIveCD вставить и попрбовать с него загрузится - он загрузится до конца ? - без ошибок? Осбоенно виндовый LIveCd

[Alexz]

LiveCD грузиться и Ubuntu (пробовал 9.04 и 8.04) и Windows. Дело в том что в висте привод нормально функционирует, а вот в убунте 9.04 после установки отрубается. 8.04 или 8.10 не хочу пробовать, так как надоело ставить. Итак со скрипом поставил.
Про dmesg не догадался. Попробую выложить что пишет.

Как я понял возникло какое-то исключение (Emask 0x0 SAct 0x0 SErr 0x0 action 0x6), которое и привело к "отключению"

Дабы не создавать новой темы, хочу задать вопрос на подобную тематику...
Приобрел недавно ноут и есть подозрение на неисправность в нем оптического привода  - вроде как и работает, но наблюдаются иногда ошибки чтения с CD-R диска.

Подскажите, пожалуйста, есть ли какие-то программы, чтобы провести тестирование привода на предмет корректности чтения/записи данных?
