Initialize RAID 1 (mirror) without data lost

[roglopes]

Hi,

I've the Linkstation LS441DE with only one HD that already has files on It, I'll connect a second HD to configure these 2 HD as Raid 1 (mirror).
When I set this raid array as raid 1 (mirror), the data in the first HD will be deleted by the Linkstation S.O.?

Changing from JBOD to RAID 1

Hard drives that aren't in a RAID array will have the status "Normal". You must have at least two drives that are not in a RAID array to build a new RAID 1 array with RMM. Building the RAID 1 array will save the data on one of the drives and overwrite the data on the other drive. You will be able to choose which drive's data to keep.
