Buffalo NAS making random noise

Not really any other way to describe it, it would be best to explain the noise phonetically, as a "pok pok" kind of noise, sometimes close together, sometimes a second or two apart, every few minutes. Drives themselves appear fine, health check shows all is well, just curious as to if anyone else has encountered such behaviour?

Exact model is Buffalo LinkStation 520 2TB as I didn't need a huge amount of storage, just something accessbile on the LAN.

THanks.

If some bad sectors have arisen the drives algorithms will keep trying to re-read those sectors and eventuality mark them as bad, so it could be what you hear as it continually seeks.

If this is the case i'd be extremely disappointed as this NAS is only a few weeks old, and has made this noise since day 1. I just thought it was part of normal operation, but recently started to question this, hence the post here...
 
OK I was going to ask if new but something told me it was not and the way it makes the noise does not fit bellow.

Most new HDD's (I use WD) have a new feature that is a PIA and sound like the above fault, the head seeks at idle every 3-5sec and I had to get rid of 2 new 2017 WD Red PRO's due to the noise and go back to 2 2015 WD Red's

According the the devices in-built health check, the drives are TOSHIBA DT01ABA100 which appear to have mixed reviews but generally seem ok for NAS usage. How hard would it be, if it were the drives giving issue, to swap them out with a pair of quality drives, I'd assume I'd replace one drive at a time and rebuild the array each time, or is it more "magic and dragons" than that?
 
Well if the Raid is Raid 1 I would say it would rebuild I have done so to test the theory (not a NAS but a Ext 2 Bay Raid Caddy with) and even a single drive (other pulled from Raid 1 to test) was seen by Windows where as some claim many devices will not work with single drive after pulling one.

To have to swap HDD's on new NAS is not ideal.

I had 2x 4TB Raid 1 and I can tell you it took ages I ended up laving it overnight (sleeping so not sure how long) but to rebuild the near full drives.

Now I have 4x 6TB Raid 10.

What brand of drive would you recommend, looking around the Seagate IronWolf drives seem to get solid reviews?
 
Honestly today with many having that annoying feature I would not be sure.

I got rid of the drives as I said above and more recently bought 4x 2nd hand (new unopened) on the Bay, the guy had 6x 6TB WD RED's for sale I bought 4 of them due to the Date Of Man was 2016, I would not have taken the risk if 2017 onwards.

That seeking noise aside the Red Pro's were louder @ 7.2k rpm even more so than my older WD VRaptors @ 10k (not sure why) so I opted to stay on Red's @ 5.4k rpm.

So I have the quieter ones but outside Ext backup all my internal Drives are SSD's 1x 512GB Windows, 1x 1TB Games, 2x 4TB storage (so 8TB in Windows Storage Spaces).

Thanks for the advice, it seems a common thing to be able to hear heavy read/writes, guess I'm just so used to SSD/NVME drives now I'd forgotten how clunky mechanical drives can be. I found a workaround, dug out an spare TPlink unit, and moved the drive out of the study! Many thanks for the advice, will bear this thread in mind for future :)
 
The plot thickens, it would seem. Randomly got a warning message from the NAS stating that it could not be accessed, no amount of messing around would get it to show in the NAS app, had to turn the unit off and wait a bit, it reappeared once turned back on. Starting to lose a bit of confidence in this now, how the hell do you replace a NAS which, at this point, has personal and financial data on it???
 
ASAP. :(

I would upload important file to the cloud , everyone has at least a 5-15GB (depending on when and how you got it) if you are on Windows 10 due to OneDrive.

I had 35GB free and sub to Office 365 so that an additional 1TB.

And pay Google (Google Drive) £16PA for 100GB (but now 200GB is better priced).

I've raised a support ticket with Buffalo directly, see what they have to say. I've moved all items back to a spare 500gb drive I had but I feel like this whole thing has left a bad taste in my mouth.
 
well, after a day of back and forth with Buffalo tech support, I have a drive that's now whisper quiet and toally behaving itself!!! Firmware update on the unit, followed by a tear down and rebuild of the array and it all seems good again, can't even hear the thing doing read/writes :)

I'm not putting anything of value on it for at least a week, but so far, so good!!!!
