Wiper Program Problem?

[lettuce]

I have just done a fresh install of Windows 7 on my new OCZ Agility SSD 120GD disk, i have only installed my nvidia drivers and AVG. i have download wiper 0525 (is this the latest version), i run the wiper.exe file and it asks me to press 'y' is i agree to the terms, upon pressing 'y' i get the following message

Wiper cant be run on drive a:\
Wiper cant be run on drive b:\

etc all the way to drive J:\

and then says,

"wiper cant be run on all drives in this system
to exit, press any key"

why isnt wiper running properly, i dont have to disconnect all my other harddrives do i in order to run wiper?

Nah, i just figured it out, i need to run it as administrator.

Another question, i understand that windows 7 by default should disable:

Superfetch
Defragger

But i should also turn off:

windows search indexing service
drive indexing

In order to get the best performance out of the SDD, where can i find these options in Windows 7 to turn off?
