Hello FredJohn,
Any disk that you will use as a replacement of an existing one or adding to an existing volume of the NAS should be fresh, formatted and no partition.

We don't recommmend that particular backup strategy.
That said, you need to power down the NAS, remove both existing disks, and then insert the "backup" drive by itself.
Then power up the NAS, and it should boot normally. You can then recover your file.
Finally, power down and insert both of the original disks into their original slots and power up again.

It sounds like you don't want to extract data from the old disk, but rather use it as a backup (shadow copy)? This strategy is particularly risky, as you might not have all the data on a failed disk so recovery might be impossible.
In any event, I believe simply inserting the drive whilst the unit is on will automatically start the format process of that drive. With hot swap, it formats the newly inserted drive.
You should have alternative backups before starting this.
