Rescue from failing drives #24146691

I've PMd you with text pasted from what look to be the relevant logs. Also I attached a zip file of all logs, exactly as created by the diagnostics in Front View, as indicated in Useful Links. I'm just waiting for my new drives to be delivered by mail and the NAS remains powered down. Depending on your assessment of the logs, I'm minded to try the USB backup first. If that fails then I'll resort to dd_rescue as you recommend. I have just realised from another thread entitled "Will my NV+ need a factory reset" that I may need to reset too, because I'll be inserting 2Tb disks and don't think I have 4k sector alignment as start sectors are not divisible by 8, in spite of running RAIDiator 4.1.7. Is that correct?

If so, it seems the strategy would then be to restore from USB backup to the two brand new drives and forget about synching from the old failing ones. Thanks again
