Друзья, помогите, пожалуйста, решить проблему с внешними USB-винчестерами.
Железо: Power Mac G5, Debian 6, USB-контроллер (PCI) и два винчестера (640 Гб, 500 Гб) неизвестных производителей (точнее, производитель самих девайсов известен — Silicon Power, но я не знаю, диски каких производителей стоят внутри). Оба винта отформатированы одним разделом в XFS.
Оба винчестера монтируются и работают, пока их не нагружать. Как только я начинаю с ними активно работать (например, копировать на них информацию объёмом >10 Гб), они тут же перестают функционировать, при этом оставаясь примонтированными.

Стоит упомянуть о двух важных моментах:
— диск объёмом 640 Гб нормально функционировал примерно до конца января, после чего начались проблемы;
— на этом же контроллере висит ещё один диск объёмом 160 Гб, который работает под большой нагрузкой (торренты 24 часа в сутки) без нареканий уже долгое время.
Заранее спасибо.
