Windows Live OneCare ?'s

1 - Tune-Up has a schedule setting but no On/Off that I can find. Is there one?

2 - Tune-Up did a defrag on all three of my drives "C", "D" and "E". Is there a way to prevent
this - to have it only defrag a selected drive? My "C" drive is my working drive and I have XP
pro on "E" that I use for testing. I'd just as soon an application that I'm running from a
chosen, booted OS 'stay home'. It has NO business going outside it's installed drive -
*especially* without asking!!

3 - Backup only gives choices of to CD or an external drive. Is there a way to have it backup
to a internal drive? I installed the "D" drive to use exclusively for storing a mirror image of
my "C" drive as a backup. I may allow Live OneCare to backup there if there is a way. ??

Thanks
