В общем начал как то замечать что смонтированный hdd на сервере временами timeout делает. Т.е. Качается файл скажем с фтп 5 минут, скорость максимльна и вдруг падает до 0, стоит на 0 минуту и продолжает качать.
Сейчас это каждые 15 сек. стабильно!

Читал на буржуйских форумах что надо типо NCQ отключить прописав
/# echo 1 > /sys/block/sdc/device/queue_depth
bash: /sys/block/sdc/device/queue_depth: Permission denied
root@webmp3:/
это значит нет поддержки NCQ
