ReadyNAS 312 V+12 voltage in enclosure Internal is out of spec. (10.72 V).
ReadyNAS 312 - 6.10.8 - 2 * WD Red 2TB Bought the 312 without a PSU and it worked fine with my old ReadyNAS Duo power supply (12v 5a) and the first WD Red (this was to replace an ageing NV+ v2 also ...
When I have made that fix, I've installed a "pigtail" instead of a connector hard-soldered to the motherboard. Netgear used to ship supplies with a 90° connector, and the original Duo even had a recessed connector to help keep damage to a minimum. But, they stopped both of those some time ago. By using a pigtail, you add strain relief. Just make sure you use a grommet or other method of keeping the metal housing from cutting into the pigtail wires.
I woke up this morning and my RN312 was back in 'degraded' status with a log full of 'too many ATA errors ... 40 in the last 30 days.
As 'disk 2' was now in 'failed' status I started a return with Amazon (disk was only 5 months old). I then explored the logs some more and found that the old 'low voltage' problem had recurred.
So, I guess that is what was causing the disk errors. (disk 1 has 0 ATA errors).
Is there any way I can 'reset' the ATA errors, reuse the 'failed' drive and cancel the. Amazon return.
Cheers, Aidan
The ATA error count is stored in the drive and I do not believe any of the drive manufacturers have provided a means of clearing them, even though they can be caused externally. If your drives are of the same model, then I do find it hard to believe that a voltage problem would cause them on one drive and not the other.
When you say the drive "failed", do you mean in the vendor's diagnostics or that the NAS has marked it as failed? AFAIK, the ReadyNAS will not fail a drive for ATA errors, so if it is the NAS, then I think something other than the voltage is failing.
Hi Sandshark
Thanks for the information on ATA errors and their location.
The NAS had marked the drive as failed and marked the volume as 'degraded' (i.e., not mirrored).
I measured the input voltage on the mainboard connector as 10.7v while the centre pin of the connector was 12.?v. I re-soldered the center pin to connector leg connection and seem to have solved the problem.
I re-inserted disk 2 and the NAS rebuilt it overnight. System seems to be fine now. No more system voltage warnings today, so I cancelled the Amazon return.
Cheers, Aidan
I suggest running the vendor diags (Seatools or WD's Dashboard). If you can't do that, then run the disk from the volume settings wheel.
