Медленно работает SATA винчестер

Приветствую всех любителей сей замечательной ОСи!
У меня возникла следующая проблема - слишком медленно работает винчестер...
Вот вывод hdparm:
hdparm -tT /dev/hda

/dev/hda:
Timing cached reads: 3648 MB in 2.00 seconds = 1823.97 MB/sec
Timing buffered disk reads: 10 MB in 3.05 seconds = 3.28 MB/sec

и вот:

hdparm -iIv /dev/hda

Я никак не твикал винт. Просто поставил систему и заметил, что она как-то медленно работает, "подвисает" приопределенной нагрузке... Помогите кто сталкивался с подобной проблемой!!!
