У меня жесткий диск WD Caviar SATA 320 ГБ на настольном компьютере 2007 года.
В последнее время во время активного использования происходит случайное вращение вниз и вверх (например, потоковое видео с него: диск будет вращаться и снова вращаться через пару секунд, в течение которых видео приостанавливается).
Это возвращает плохие воспоминания о многих неисправных дисках - однако SMART, похоже, предполагает, что все в порядке.
Это происходит в среднем один раз каждые 1-2 часа.
Я побежал:
sudo smartctl -t long /dev/sda
И тогда sudo smartctl -H /dev/sda дает мне:

Я попытался переключить оба кабеля питания и SATA, но безрезультатно.
У меня, конечно, нет важных данных на этом диске, но я не особо рассчитываю на время простоя, которое может возникнуть из-за сбоя диска.
Насколько вероятно, что мой жесткий диск вот-вот пойдет в гору?
Может ли это быть блок питания вместо этого?
Могу ли я провести какую-либо другую диагностику?
