WD RED Smart bad info?
Hello community! Last April I bought two WD Red 4TB WD40EFRX hard drives (I bought them with a difference of 7 days) and replaced them with the two 2TB WD Green I had in the Readynas Ultra 2 with...

Could a supposed incompatibility with the readynas cause this failure in SMART? Because this happens on both hard drives. I honestly find it extremely strange, but I believe anything.
I don't see how. The drives are maintaining this data, and you are seeing the same low values when you do the readout on Windows with a different tool.
Also, lots of folks use these drives in Ultras, and I haven't ever seen this reported.

Arrived at this moment, I am worried about the most important thing: the stored data, I do not know if I can trust the SMART of the hard disks (I have backup, but I am interested in the reliability of the NAS + hard disks).
Without knowing the cause, it's difficult to say how big the risk is. You could try replacing one of the Reds with a Seagate Ironwolf I guess. That would reduce the exposure.
Another strategy is to run scheduled disk scrubs on the NAS - they do serve as good diagnostics, though it is tricky if you can't really on SMART.
Hello again.
I was talking in some emails with Western Digital, and finally, I made reference to this netgear thread: they phoned me, I insisted that the SMART should be autonomous of the device. They have insisted that hards disks work for them, unless the Western Digital tool (WD Data Lifeguard Diagnostic) says that the disks are in poor condition (and therefore the warranty could apply). They have told me that many incompatibilities can cause this type of events on the disks and that there aren't new versions of the hard drive firmware. Although it may be a bad read of the SMART in the NAS (I think it is false), I insisted that I read the SMART with CrystalDisk Info: They tell me that they trust this tool, but that the RMA is only provided in the disks if the Western Digital tool is used and indicates that the hard disks as failed.
I hope in the next few days to stop the ReadyNAS and check the hard disks again (I'll post it in this thread of the Netgear community). However, I don't have rare software combinations (I have the latest official software version of the ReadyNAS Ultra 2: Raidiator, OS6 has never been installed), I can provide the logs by private message to a moderator / administrator of the forum if necessary.
However, the BIOS of the ReadyNAS Ultra 2 has never been updated, I do not think this is a problem for the SMART to increase the hours correctly. The bios_ver.log file indicates the following: 09/08/2010 ReadyNAS-ProUltra2 V1.4;
and apparently there is a new version 11/02/2011 ReadyNAS-ProUltra2 V1.8. Are there any details of what problems are patched? Should I update it? I understand that this BIOS update is completely manual and is not mandatory ... because automatic updates have never suggested it. Is there a reason?
Many thanks again.
