ReadyNAS 316 ATA errors during data reshaping / resync
About 36 hours ago I replaced an ST4000VN000 (4TB) with an ST8000VN0022 (8TB) in my ReadyNAS 316 (Firmware 6.9.2). 4TB drive had not failed, just a pre-emptive swap, it was 4.5 years old, and I also ...

Though the ATA errors might be a side effect of the same failure that is giving you the uncorrectable errors.

Thanks for the replies. The drive is not "new", but it is still under warranty. It has been in the unit under a year, it was probably sitting here on standby up to 6 months before that (I buy a new drive every time a drive goes into the unit, so there's always an unused spare here). I doubt the NAS itself is still under any warranty, but I'll check the purchase dates.
Sounds like no one has any insight into this scenario specifically (other than the drive might just in fact be bad), so I've decided to let it go for a bit as an experiment (all the data is mirrored to another NAS as well, so worst case I've just got to rebuild this one if it all goes pear shaped).
I suspect the drive is not bad, and the errors were just a resync anomoly, so I'll leave it a few weeks and see if further errors show up. If nothing after a month or so, I'll pull the drive and swap it anyway, and run the diagnostic tools on it. Whatever the outcomes, I'll post them back here.
