I decided to split disks 1 and 2 as two jbod. I removed all disks, cleaned disks 1 and 2, did a factory reset and set them up as 2 jbod volumes. Can I now safely return disks 3 and 4 without losing the data?
Did you export the two jbod volumes before you removed the disks?
If not, then try powering down the NAS, removing disks 1 and 2, and booting up the NAS with only disks 3 and 4 installed. The RAID-0 volume will show up as failed/not present. Then see if you can export the two jbod volumes.
If that works (or if you previously exported the volumes), then power down, insert all disks, and power up again.
Thanks for the quick reply. The current situation is disks 1 and 2 are installed as 2 x jbod and I am restoring files to them as I write. So can I now return disks 3 and 4 without losing the data on them? I'm just worried that the factory reset may have done something that causes the nas to format them instead of simply mount them.

No, that is not what I said. Go back and read post # 2 again. Pay particular attention to the need to export the volumes.
You can of course back up the files on disks 3 and 4 when you boot up the system with only those disks in place.
The raid 0 volume no longer exists. I have now got disks 1, 2 and 4 all as single jbod volumes, and all are active and saving data. So my concern is can I return disk 3, containing data from before starting this evolution, into slot 3 and have the shares on it available again, or will it be reformatted by the nas? I am aiming for 4 individual jbod volumes.

How many times do I need to answer this? Here is the step by step:
- Power down the NAS
- Remove disk 1 and 2, add disk 3 and 4
- Power up and reboot the NAS (with only disk 3 and 4)
- Go to the volumes page in the web ui. You should see the volumes on disk 3 and disk 4 as healthy. The original RAID-0 volume will be inactive
- Optionally back up the files on these two disks
- Click on the volume settings wheel for disk 3 and choose Export
- Click on the volume settings wheel for disk 4 and choose Export
- Power down the NAS and reinsert disk 1 and 2
- Power up and you should then see all four volumes with no data loss.
