RN104 Data degraded on brand new disks
Okay so I have a RN104 4 disk readynas. I have had problems with this one before with killing my disks (was told my disks were not supported so reason for failure), so now i finally bought 4 new 4T W...
Thanks for your input. I took out the disk and ran it with WD own diagnostic software and it also gave me reallocated sector count errors. Now this disk is brand new with warrenty so i will not be messing with it but return it to get it replaced.
But regarding the fact if Netgear hardware is actually to blame? I have 3 friends that all have Synology NAS, one of them is 7 years old and runs with old 500 gb disks AND they were all used when mounted in the NAS at the time and of various brands. Never had any issues with his. Another friend have 2 NAS of the same brand, one will 4 year old 2TB drives (4pcs) and one with various size drives (4 pcs) running on the 5th year, one problem only and that was a 250GB drive that was like 10 years old when it died. The third guy has 3 2TB drives in his running for 4 years now without problems.
Myself opted for Readynas, can't even remember why any more, maybe cheaper and during 4 (soon 5) years i have now replaced some 9 disks on two NAS (NV+ v2 and RN104). Unlucky can take care of some of the drives.. but i still feel that hardware has to be a factor here. Even with recommended drives.. And to top it... this morning i look at the logs for my NV+ V2 and now a 3TB WD Red, less than one year old is starting to show errors, that means soon i will have to replace disk no 10.
So with all this in mind, i would say that hardware does play a role or new disks are just so bad these days.. I have a 1.5TB 8 years old disk still running in the NV+ V2 and that one have had no problems and it's the only reason its still in that NAS..
Anyway, thanks for your input. Lets see what happens with i get a replacement disk.

As previously said, this is a pure HDD error, they're not generated by the NAS.
If your HDDs are too hot due to poor cooling of the chassis, or if the HDDs are always vibrating because of poor mounting in the chassis, NAS or PC, power supply issues, etc., it may indirectly cause some HDD problems. But unless you have obvious evidence of this about the chassis the HDDs are in and that pretty much ALL the HDDs you have always have the same behavior, then you can rule out the chassis from having anything to do with it.

Correct.
FWIW, I started deploying WDC Red drives in my various ReadyNAS in Nov 2012. I'm running 11 right now, I've seen only 1 Red drive failure over the years. These are in a ReadyNAS Pro, a Duo v1, an RN102 and an RN202.
You might try a different supplier (perhaps there is some damage in shipping/handling). I'd also take a look at disk temps, and check to see if the chassis is placed somewhere where experiences a lot of vibration.
Thanks again for all your input.
My NAS and servers are stored in a cool room where we have all other electric boards and fuses, also our fiber connection enters our house there and so on. And temp on drives is about 40-42C / 104-107F on the RN104 cpu at 60 The NV+ V2 drives are at 32C / 89F but CPU is at 30C/86F so.. they are not running hot, except that the RN104 is always hotter than the NV+ V2.
Vibrations.. not likely. On a solid shelf mounted on concrete wall..
Shipping and handling.. well i can not say. Drives have been purchased from all over the place.
I really hope I have just been that unlucky dude the lightning strikes a couple of times. Just sent off my other 3TB WD red also as its good on the warrenty still, but had to send it with UPS so that will take a couple of weeks... Resyncing the RN104 after getting my replacement 4TB and crossing my fingers i dont get any more errors now for years. Because i do like my NAS, i also think they have a nice design and are pretty robust and i can keep great loads on them and they deliver.
I guess i should not push my luck and continue my backup jobs before the resync is done... in about 80 hours.. blaaa
Anyway, thanks for your input.
