If you're disconnected, you can still come back from the server.
I was to do an clean one without the taskbar, but I couldn't get as transparent. If you, for example, you shut down computer with steam turned on, it will not work and will validate cache again. So the game must keep the caches from you equal from the steam servers.
If there are individual files you can narrow the issue down to that are not huge, try deleting them and re-downloading/verifying to see if it helps.
Restarting Steam between attempted verifications may help.
