get repeatedly message "We have discovered that the hard disks from another NAS"

[UweE68]

Hi, I'm completely new is this XPEnology topic, so please forgive me if this is a very stupid question.

 

I have a custom build Intel hardware and worked thru the tutorial to install DSM 7.

 

At the beginning everything looked quite good. At first boot I had no HDD installed. DSM claimed that it needs HDDs (surprise....)

So I installed three WD NAS HDDs, that were completely empty, not formatted at all.

 

After I booted again I got the message "We have discovered that the hard disks from another NAS...." Only option is "Restore". Takes 10 minutes and I end up at the same message, Tried three times now.

 

Any ideas?

 

Thanks
