I took that to mean that at every boot up [in my language also means Restart or cold startup, not a log out log in] Disk First Aid checks the startup disk. Is this not so? This is why I have rarely bothered to run DFA on my startup disk, assuming it has regularly been done every time I restart which I do every day. I do understand that you can not run DFA on the startup disk once the startup process has completed. ......... Peter Sealy Thurgoona AUSTRALIA
