WD RED 2TB do not sync with older WD Green 2TB on RNDU 2120
I have a RNDU 2120 (ReadyNAS Ultra 2) with 2x2TB. It came populated with 2x2TB WD green HDD (WDC WD20EARS-00MVWB0) Firmware RAIDiator 4.2.31 and 1024 MB memory After some years the hard disk drive N...
I suspect that the number of sectors on the old Green drive doesn't match the sector count on the Red. If that's the case, the volume won't sync. You can probably confirm this by downloading the log zip file, though it may be quicker to simply boot up with the Green drive in disk 1, and slot 2 empty. Then try to hot-insert the Red drive again.
If that fails, then the only recourse is to back up the NAS, and do a factory reset (with only the Red in place). Then restore your data from backup. You can then try to sync the remaining green drive to the Red (which will work if the green has a few more sectors).
Thank you for your quick response.
I did the hot-insert of the new hard disk like 4 times (each time shutting down and restarting the NAS with only the "old" green drive and then inserting the "new" one). I have tried starting with it alone in slot 2 but like that it appears as "dead".
I never started the NAS with both drives in place as I fear that it decides that the good drive is the new one and thus errasing al my valuable data that is still alive.
How do I reach the "log zip files"'? I see that in the FrontView web i/f is an option to downoad the logs, but as far as I see/saw no one says nothing regarding the sectors on the drive.
The easiest way to do the backup is connecting an external drive over the front USB port and then commanding it through the FrontView web interface?
Thank you again for your knowledge and your time!

The new Red might be dead. Can you test it in a Windows PC using Lifeguard? If not, perhaps just exchange it with the seller (WDC will give you a recertified disk under warranty, the reseller will exchange it for a new one).

disk_smart.log shows the SMART data (disk health). partition.log should give you the sectors for each disk.

That will work, and the front port is the USB 3 port. You can also back it up over your network (using drag/drop to a disk connected to a PC).
