Areca RAID High Pitched Whine/Tone
So, I’m pretty sure I know where this goes, but I’ve got an old Areca ARC-4036 that’s been in constant use since circa 2008? Over the years multiple drives have been hot swapped due to impending drive failures, etc. Recently, an extremely high pitched whine (think tinnitus) will occasionally start happening for random amounts of time. If I gently reposition the box, it will sometimes stop, sometimes not. I’ve run SMART tests on the individual platters and can’t come up with any faults, so I’m wondering if it’s a failing capacitor or something? I haven’t had any hits in performance, or noticed any other actual negative effects from it, but am starting to worry in the back of my head that it’s something more ominous. Obviously, probably the most prudent thing to do would be start looking into a new RAID box for myself, but figured I’d see if anyone else has run into this and knew if it had any likely culprits. Thanks!
