Hard Drve Failure
I got an email notification this morning saying
"Disk test failed on disk in channel 2, model WDC_WD4000F9YZ-09N20L0, serial WD-WMC1F1268766."
But NETGEAR RAIDar diagnostics shows the drive is healthy
I have already replaced drive 2 with a spare 4TB and all is back to normal, if another drive fails I think it's best I look for a different drive and will replace the next failed 4TB drive with either a 6TB or 8TB drive.
I don't know where I would backup 6TB of data too? one at a time every week should do it and I'll bite the bullet and go for 8TB drives, model Seagate ST8000VN0002 US$550 each with a 5yr warranty.

I suggest testing it with lifeguard.
Hi claytonb,
Before pulling out and replacing the said drive with a new one, you may also want to take a look at your system device logs to check the health of the drive with the corresponding S/N (serial number).
Kind regards,
