Preclear from main menu

[Nokoff]

Hi Guys, using the latest beta 10a. I put in a new drive and noticed a link that seems like it should pre-clear the drive before I pop it in the array (I want to avoid waiting the duration of clearing the drive whilst my array is stopped.)

 

The link is: http://tower/Main/Preclear?name=sdd&file=/tmp/screen_buffer and it appears to the left of the drive name with three plus signs, ("+++").

 

Screenshot attached. When I click it though nothing appears to happen. Is this supposed to have functionality to clear the new drive without stopping the array? Curious to know if this functionality is still to be implemented.
