When I restart my pc the vault which is on my pc causes a lot of disk trashing for about 10mins. This slows everything down. It is like the whole vault is being indexed. Why does this happen? Am on 2012 sp4 but was the same on 2010 sp5 and earlier. Also (due to this?) when I first save a part even if it is small the disk trashes like mad too. After that things are fine. Attached are 2 pics showing vault settings and disk activity. One thing  that I am unclear about is the setting to validate vault which has a thick box and then the radio buttons for a)next startup b) every startup. I am assuming if the box is unticked no valitate should occour.
