Сломанный UDMA

[daniel]

Здравствуйте!

Имеется старенький IDE жесткий диск SAMSUNG SP0802N у которого имеются проблемы с UDMA. Я отключил поддержку UDMA в BIOS'е для данного диска, т.к. если ее включить то grub стартует раз через раз, а если и стартует то через n-ое кол-во времени. Но ОС при этом загружается долго и ругается на этот жесткий диск.

Вот вывод команды kern.log | greep ata (последняя загрузка)

Если я правильно понимаю данный вывод, то тут ядро переключает режим работы жесткого диска и диск нормально работает только в режиме PIO4 что и не удивительно. По сути проблему долгой загрузки можно решить, принудительно задав режим PIO4 по умолчанию. Как это сделать?

Проблема точно в железе т.к. у меня два диска этой модели и UDMA не работает только на одном. Можно ли вылечить, т.е. завести режим UDMA на этом диске?
Примечание: пожалуйста не предлагайте замену жесткого диска это крайняя мера.

Может пригодиться вывод hdparm -iIv /dev/disk/by-id/ata-SAMSUNG_SP0802N_S00JJ40XB55782

Я так понимаю это отключит DMA для всех IDE  интерфейсах, желательно конечно отключить DMA только на одном устройстве.

Передача этих параметров не меняет результат.
