I found where it was claimed it doesn't work. This is the link. https://askubuntu.com/questions/1007716/formatting-an-ext4-partition-with-a-16kb-block-possible That is a few years old and things may have changed. I also saw similar info elsewhere. I may try it just to see if I get the same output. If it works, fine. If not, then we know. Odd it would have the option but not allow you to use it tho. :/ Dale :-) :-)
