Moving hard drives and RAID
I'm perhaps overthinking this, but I wondered if I could run my plan by the community for feedback. I've got a ReadyNAS 102 with a 4TB hard drive, and I've just bought a 312 with another 4TB hard...
That should work. Although with only a single disk installed, you don't need to (can't??) set it to RAID0.
I assume you are wanting to move from the RN102 to the 312? What is your final goal, to run the 312 in RAID0 for 8TB of total space (without redundancy, with all the data from the RN102?
I think it might even be possible to just take the drive from the 102 and insert it into the (empty) 312, and keep all your data. I'm sure someone else can confirm whether it is possible or not.

That's what I'm thinking of aiming for, yes. If I can't set a single volume to RAID0, how do I do it? Won't it reformat the drive if I do it after installing the second drive?

I've got another thread elsewhere with a long, sorry tale as to why that doesn't seem to be working for me and which prompted me to buy the new 4TB drive in the first place (I hadn't really wanted to spend the money). I think it might have been solved now (need to test it tonight) but since I have the new drive...

That is a bad idea. If either drive fails you'd lose all your data on both drives.
A better approach would be to switch to flexraid and then add the second disk as jbod (a second volume). You'd need to set up shares on each volume - a minor inconvenience. But then when a disk fails, you only lose the files on that disk.

That's an interesting thought. So how does the process work? When I've got a single disk in there it seems to be labelled as JBOD already. Can I simply install another and choose JBOD and not have to reformat any data?
