Hello , Happy cristmus&new year wishes in advance. My problem regards to my brand new wd hd creating noise on frist boot since I had loaded OS(xp) . Whenever I pointed mouse/cick an application/open aprogram it creates grinding metallic sound.One of the two LEDs(not the power indicator, the other) blinks in syncronisation with grinding sound. The sound stops on loading the program on the moniter(I think data arrival on RAM). some clicking sounds comes even when the system in idle. Is the HD comes damaged?. Should I replace HD?.Of couese the retailor assured me to replace if damaged. Model of HD-WDcavior blue 3200AAJS 00L7A0. OS-XP pro sp3. computer make- lenovo desktop 9215 12Q. Thanks Mr raptor pa for your previous answers.I oppolozise for not responding your previous answers since my system's old HD was dead. Thanks again.
