FWIW, you can also directly migrate the disks to a Pro or Ultra Plus platform.

Do you need to offload data?

BTW, if you purchase a used X86 OS-6 NAS, you can mount the Ultra volume as read-only. After off-loading you can complete the OS-6 setup, and then restore the data from the backup. So that is another option.

If you power up with no drives, does RAIDar report a "No disks" status, or is it unreachable?

It could be just the power brick, and replacements are cheap, so it might be worth a shot.

Could there be an issue if the drives / data is encrypted?

I went to a computer repair mob today to try another power supply as Sandshark suggested could be the quick fix and unfortunately thats not the issue, but they took the drive and hooked it up and said the data was encrpypted and swapping it to another readynas wont help??

Is this true?

I dont know what they hooked it up to, likely just a spare bay in a computer.

  Did you encrypt the volume? (If you don't recall, then you almost certainly didn't). If you did, you'd have a USB encryption key connected to the NAS.

  A Windows PC wouldn't recognize the format unless linux tools were installed.

    If the data volume is encrypted, the NAS still boots to a "waiting for ther key" state since the OS partition isn't encrypted. So that doesn't sound like a match to your symptoms (though it does sound like maybe you should find a new computer shop).
