How to stop the compiling?

Hello:  is there a way to stop - to force- the live hub from compiling?  Not being used for movies or streams at this point, simple data storage over nw. I deleted files on a USB drive directly connected to the hub, so I suspect the WD sw is now recompiling.  Both drives (hub & its connected USB drive) seen fine on the nw.  Thank you.
