Disk failed - re-synced, disk failed again - do i really need to replace the disk?
Can anyone help me make sense of this.
2 of my disks have been reported failures in the past week. I've ONLY just begun to use Chronosync to now back up my computer files to it. (There are a lot of files, in the 1M+ small files/ development files etc). It is only in this past 2 weeks i've been trying to perform a regular sync from my computer to have a laptop backup. I've had the nas for some time and its been generally just movie storage. ;)
The issue
Disk 1 fails, i resync, the disk 4 fails, i resync, then disk 1 fails again, resync
- how can i check if the disk is bad that i need to replace it?
- more so, if it is a bad disk and needs to be replace, what could be causing this type of tag team failure...?
There is a snippet of the log.

These are Seagate "Green" drives. Seagate Ironwolf (or WDC Red drives) are better choices for NAS use.
I'd replace disk 4 now.
If you don't have a backup of your NAS files, then you should take care of that without delay.

Are you using "green" drives? That is precisely the kind of problem they can create with their self-parking behavior. But the drives may really be having problems. A resync is hard on a dirve, so resync for one could cause another to fall over the edge.
The best way to test the drives is with the manufacturer's tools on a PC, either directly connected to a SATA port or using a USB cradle.

I'll purchase a cradle and do a test the next time it fails.. thanks for the advice.
