ReadyNAS NV+ Disk Failure

I google the forum to get the user experiences on the disk model before I buy. Experiences with ST2000DM001 are "mixed" Personally I've been buying WDC Red drives.

What are the SMART stats on disk 1?

Thanks for the reply, I will buy a WD RED WD20EFRX and see how it goes

What do you mean by the SMART stats, after syc the b=new segate drive reporting as a failed disk, the light flashing on it's bay.

Well I can confirm it was the segate ST2000DM001. I purchased a new 2 Tb WD RED WD20EFRX and it syn fine and has been working fine since. Time the segate model was taken off the hardware compatibility list I think.

Glad it is working now. SMART+ stats are found on the health tab of frontview. You can google SMART and get some guidance on what the stats are good for.

thanks for that, I had never clicked that button before I had mainly relied on the logs for information, just goes to show you learn something new every day :>
here are the current stats for the 3 of the 4 drives. Drive 1 is the new drive and 2,3 and 4 are the pre existing segate drives. Disk 4 looks to have some relocated disk errors and I have had a couple of notifications regarding this drive in the past. Over the next month or so I might replace all the remaining drives.

Thanks for your support

The spin retry counts are something to keep an eye on - that is the number of times the disks didn't spin up to the operational speed.

lp stat events are something Netgear added - you have lots of them on disk 1. I'm not sure if that is something that matters or not, though you might keep an eye on how fast they increase.

Reallocated sectors, uncorrectable sectors, and current pending sectors are the big three parameters, and they all are 0.
