first, let me just state that there are no bad sectors.
OK here goes, upon installing redhat 7.1, and even in the install, my HD seems to work constantly producing a static noise, well, its not the "moving files", "loading stuff" noise, its just like something that could've come out of Ski or Die. vrrrrrrrrr. schhh. its not thrashing, and its pretty high frequency. even when I move my mouse. Its driving me mad, I've tried hdparm (aboutishly every parameter there is), and now I seek counsel here. _ANY_ response will be appreciated.
