Resetting disk array

[sdamaged]

Hi,

 

I'm running 6.4.0  on my test server but forgot to set the disks up encrypted.  How can i erase the entire array and reformat the disk as encrypted? I don't care about losing data

 

ive tried going into tools and choosing new config,. but  the array seems to rebuild (which is an amazing testament to the redundancy of unraid!) but i want it blown away

 

Any ideas?

 

thanks

Sorted it! Changed file system type on each drive and then formatted.  thanks
