Swapping HDDs between different ReadyNas Duo v2
I have a RedayNas Duo v2 that will no longer mount its 2 HDDs. After a power outage and a successful synchronization of the RAID X configuration (started by the NAS itself) and a scheduled power down...

The OS is on both disks, but the system normally boots from the first disk it sees. So I would try booting up with only disk 2 (in slot 2) and see what happens.
Stephen, many thanks for your reply.
I checke d both NAS, they both say ReadyNas Duo on the front (hence they are v1) and have a label on the underside that says v2 (this still means they are v1, per what you say).
I have changed the power adaptors, no change in behavior though.
Raidar will find the troublesome NAS but won’t say what firmware is on it. The line is blank. While the other NAS (with two good HDDs) will state the firmware version in the overview page when you start Raidar. So I have no way of knowing what firmware is on the troublesome NAS.
The HDDs in the troublesome NAS are the same make and model but one is 3 years young than the other. I have a 3rd HDD of the troublesome NAS (before it became troublesome) that I keep alternating in the same NAS every 3 months and I keep it in the office in case my house burns down. Also this HDD is same make and model.
I keep a yellow sticky on that 3rd HDD with the date, the NAS it came from and what bay it was in, here in this case it’s bay1. I did not do any firmware upgrade in the last 3 months.
What shall I do first?
Try the 2HDDs of the troublesome NAS in the good NAS?
or
Try to reinsert the 3rd HDD taken out of the now troublesome NAS 3 months earlier when the NAS was ok?
Even losing 3 month of data is painful.

I'd
- power down the troublesome NAS and removing disk 1. Then power up and see if it boots.
- If that fails, you can then power down, and just insert disk 1 (removing disk 2). See if that boots.
- If 1 and 2 both fail, then update the firmware on the working NAS to 4.1.16 (which is the latest), if it isn't running that already. Then power it down, remove the disks, and migrate both disks from the troublesome NAS. Power up, and see if it boots.
