Ok that is odd. I had to reboot the unRaid server, because it said all the drives were unknown, then I stopped the array and NOW I see that I can format the drives in one bulk go. I'll keep ya posted.
Ok I too hate to revive old threads, BUT just to be clear. I am using unRAID v6.12.6 and I stop the array and in the "<Main>" menu I see the Array Devices. I click on "Disk 1" and that opens up to the first tab under /Main/Settings/Device?name=disk1 but I do not see any means to format a disk nor to set the file system type there. Partition type just says "Unknown" - and from what I see on the "<Main>" page I do not see any text that states format. I must be missing something really basic.
Is the page : http://unraid.category5.tv/ broken I just get two lines at the top and nothing else :
