Readynas Duo V1
Originally had system set up as 2 mirrored 2TB WD Green drives. System stopped booting. Removed both drives and used externall enclosure to inspect drives with R-linux. 1 drive not accessible and ...
DO NOT install the old drive alongside the new one in that manner. You will lose your data.
Assuming this was an XRAID volume, you insert just the old working drive and let the NAS boot. At that point, it would be good to make a backup before adding the second drive since the RAID sync process puts stress on the drive and failure of that other one is always a possibility. It's not really that important it be in the original slot. If you have an old downloaded log file, you can find the drive serial numbers in disk_smart.log to see where it was installed.
Once you are ready to install the new drive, do so with the power on. It's content will be wiped out (thus the warning not to make your old one the second one installed) and it will be added to the RAID. While OS6 warns you the drive has data on it and again warns you it will wipe the data when you go to format it, RAIDiator 4.1.x that is in your older NAS just moves ahead with the format of the added drive when it sees one, wiping the data.
If you had something other than XRAID/RAID1, data recovery is unlikely.
I am thinking to be safe I mount the old drive inthe external enclosure on my PC wiht R linux and then copy all data to another drive I have.
Then do as you suggest. If it goes wrong then I can at least copy the data back from the backup.
As a point what format drive does the usb sockets read on the NAS?

I was going to suggest that, I agree it's a best option since you are already set up with R-Linux

ext (linux), NTFS and FAT32. USB performance on the Duo is very slow - it's fastest to transfer data over wired ethernet.
