Can you separate the RAID1 without formatting it?

We are very satisfied with the “My Cloud EX2 Ultra” there is only one question: can you separate the RAID1 without losing data or having to format it? And how does it work.

Or is it just described incorrectly in the reference on page:

Page 58

For user settings see “Saving a
Configuration file ”on page 93.

Best regards

@Idova, You cannot separate the RAID 1.
If you wish to have 2x Jbod on your device, you need to

  1. take a backup from your data on 3rd device
  2. Follow the instruction on the below KBA.
