wa sy - это что за команды такие?
Кхм !(Я ж вроде "wa" расшифровал ? )
Это из вывода "top", чем загрузку CPU смотрят.
- us - программы юзера
- sy - системные процессы
- ny - прерывания (вроде) ?
- id - общий простОй системы
- wa - ожидание операций ввода-вывода
etc...
и вообще, man top
( ;) не удержался, сорри!)

UPD:
Упс, децл оплошал.
Один только на SATA сидит, другой primary slave.
И, что-то меня терзают смутные сомнения ... где-то я ещё такое видел.
Как бы не на работе, там есть компик Arc Desktop. Что-то припоминается вроде.
Народ! Кому не лениво:
если больше одного винчестера в системе, киньте с одного на другой гигов 10-20-30, сколько загрузку в Top'е покажет ?
