Continual SMART warnings - ReadyNas Duo
I have a ReadyNAS Duo, and have had a problem for the last couple of weeks where each time the NAS boots (once a day before I get home from work) where it emails me a warning of a SMART failure on disk 2, instructing me to replace the disk. However when I log in to front view and view the smart info the disk looks fine. Here's the output:
Model: ST31000528AS
Serial: 9VPB6VRP
Firmware: CC44

Is there anything I can do to fix this? I'd probably be happy just with surpressing the warning emails for the SMART failure, so long as I still get warning emails for other things, especially disk failure.

- Do you have any USB disks connected to the NAS. If so it's likely the SMART errors are on the USB disk. I've seen some reports of this issue recently.
Edit: What did you mean by SMART failure? I think I may have misread what you said. Do you mean things like ATA errors and Reallocated sectors. If so, I did read what you said correctly. However if you meant the disk did not pass the smart self-assessment test then that's a different matter. - No USB devices attached. By smart failure I mean each other time the nas boots I get an email like this:
Disk 2 did not pass SMART self-assessment test. Please replace this disk as soon as possible.
Growing SMART errors indicate a disk that may fail soon. If the errors continue to increase, you should be prepared to replace the disk.
But as you can see from the smart output above, there are no smart errors. - Doesn't need to be SMART errors to fail the self-assessment test. Disk likely is failing.
I'd suggest you power down the NAS, remove the disk, connect it up to an internal SATA port in your PC and check it using SeaTools - OK I'll give that a go. I take it I can do that on a PC without affecting the FS, ie formatting?
Correct. SeaTools will find the drive, even though Windows will not show it under "computer" (since it doesn't recognize the format).isaac82 wrote: OK I'll give that a go. I take it I can do that on a PC without affecting the FS, ie formatting?
