Horrible coil whine with ReadyNAS 626 - any solution?
Hi,
Our ReadyNAS 626 has horrible coil whine when idling. It's so loud I can hear it 30-feet away in another room. Here's what it sounds like:

We're using 5 Seagate ST8000NM0055 8GB drives in XS-RAID confguration. Can anything be done to make this better? It's really awful. Thanks for your help!

I am thinking it might be one of the disks, and not the NAS. If so, the disk should be replaced even if the SMART stats are good.
Can you try powering down the NAS, and removing the disks? Then see if you still hear the sound.
If the sound goes away, then perhaps try connecting each disk to a USB adapter/dock (perhaps connecting the dock to a PC to make sure it spins up), and see if you can isolate the disk.

Thanks StephenB. That sounds like a good idea. These drives should still be under warranty. None of them show any errors. I'll have to look around for a 3.5 dock, We should have a couple around here. Is there any risk to the individual drives in plugging it into a PC or Mac?
I believe its been doing this ever since we set the 626 up last year and I guess it doesn't bother my partners, but it really bothers me!

Of course a drive will make some noise during normal operation. But your drives should be quiet - spec'd at ~28 db when the drive is idling. That's about the level of a whisper. If you test with the drive connected to a USB adapter ,then listen with the drive on a pad of paper, or something similar to prevent the drive from vibrating the table surface.
FWIW, the noise spec for the RN626x chassis itself is about the same as your drives (spec'd at < 28 dbm). So it should also be quiet. If the noise of the NAS continues w/o the drives installed, then it is likely a fan. That could be covered by the NAS warranty - you'd need to RMA the NAS to resolve it. I think you can set that up so that Netgear ships the replacement NAS first, so you'd have no downtime. Also, you'd need to pay for the shipping of your current NAS.
If you want objective data, there are some phone apps that can measure the noise level. To get an accurate measurement you'd need to calibrate the software - but you should still get a reasonable ball-park measurement w/o calibration.
