How long it takes to "Reformat Previously Formatted Disk"?

I want to add a 6TB disk (new disk but connected to PC to check bad sections) to my RN102, and as the HW manual says, a Previously Formatted Disks should be Reformated before using. I don't know if the disk has been formatted or not, but I followed the instruction, reset the system to its factory default settings, waited 5 mins for disk testing and 10 mins of time-out period, and then I found that they didn't tell how long it takes for the reformatting. 

In Windows OS, formatting may take for a few seconds to a few hours, but I didn't found info about it in ReadyNas. I'm confused now. If I should wait or just shut down the NAS. 

 

Thanks in advance for any suggestions and advice.

    What disk model?

     

    Is this the only disk in the RN102?  If not, there was no reason to do the factory default.  That is destructive, so any data you had on the other disk would be deleted. 

     

    Have you tried logging into the NAS? (https://nas-ip-address/admin, using the actual IP address of course).

      The reformatted disk model is WD6003FFBX, it's on the compatibility list.

      It's a empty disk, and it's the only disk in NAS when I do the reformatting. 

      The old disk (a 3TB WD red disk) was dismounted while reformatting, as I just want to add the new disk as additional space. 

       

      Now the NAS can be discovered and setup as a new ReadyNAS device on readycloud website. 

      I guess the next step is to shut the NAS down -> replace the new disk to the old one and power on -> check if it's already in Flex mode -> hot insert the new disk and set it to a new volume

      Is it right?

        You used the wrong procedure.  What you should have done is 

        1. make sure X-RAID is turned off (no green stripe on the X-RAID control on the volume page)
        2. hot-insert the new disk
        3. select the new disk, and create a new JBOD volume

         

        I suggest powering down the NAS, putting in the original disk (by itself), and powering it up again.  Then you can execute the steps above. The first step is very important, so make sure X-RAID is off.

         

        However, it will be a bit simpler if you can unformat the WD6003FFBX before you hot insert it.  You can do that in a Windows PC, connecting the disk either with SATA or a USB adapter/dock.  

         

        If you can't do that, the second disk might show up as an inactive volume when you hot-insert it.  Let us know if that happens.
