I have a harddrive that started making a constant high pitch noise. i did a SMART long test and it reports the disk is fine. The actual problem is that when I send a command to put it in standby (using hdparm) so that it spins down and stops making the annoying noise, as soon as I do, the MOBO shuts off and after I restart the machine, it says "power supply surges detected during the previous power on .Asus anti-surge was triggered to protect system from unstable power supply unit"
So, currently my belief is that the disk is fine but that's my first question. Is a constant high pitch noise a conclusive symptom of a dying disk?
But more importantly, is it really possible for a harddrive to create a surge when it powers down or should i worry about my PSU? or could this just be a false positive on the surge protection mechanism?
Try updating the BIOS to see if this alleviates a possible false positive on the PSU. If that doesn't help then you should definitely worry about it... I have seen that before in my shop on new builds before and ignored it thinking it was a false positive, only to have to replace it soon after when it died entirely.
