Seagate 8TB Archive drives (ST8000AS0002) do work

First you download the 6.4.0 beta 1 or 2 (can't remember which one it is:)

Then you install 6.2.4 or 6.3.5RC2 (both worked just fine in my experience.)

Also what firmware drives do you have? AR13 or AR15? The only drives that gave me trouble on 6.4.0 were AR15 firmware drives. The AR13 work fine.

Interesting... mine are AR13.

Did you factory reset at any point from 6.4.0 -> 6.4.0 T112 -> 6.2.4

You have to factory reset once back down to 6.2.4 (after you've installed it.)

So backup your data then once downgraded go from there.

This could be a think with the ultra models versus the pro or other models... I have no idea. I have to hook my drives up to the rn104 and see if I'm seeing the same issues (at this point they already have a ton of errors showing on the smart data so I don't feel comfortable using them... that's why I kind of feel like the firmware ruined them.. prior to that no problems.

I know what you mean!!

So far on mine the only SMART 'errors' are command timeouts (39 and 6 respectively) - and whilst being no expert I wonder if this is artifactual from it being hit with too many commands whilst the 'SMR stuff' internally catches up.

I have an RN102 coming soon so may try them in that to see if ARM v. x86 makes a difference.

Thanks for the advice. Will reset on 6.2.4. These drives are the backup of my other NASes - the idea was to eventually have 4x8TB glad I stopped at 2 until this is sorted as they aren't cheap!

Can't you RMA them if they have loads of SMART errors?? Do they pass SeaTools still??

Back on 6.2.4, thanks. Will update here - https://community.netgear.com/t5/Using-your-ReadyNAS/8TB-Drive-drops-out-of-JBOD-volume-on-6-4-0-on-Ultra4/m-p/992765#M95329.
