Hi,
if you really used killdisk (
http://www.killdisk.com), I'm afraid you're out of luck. Killdisk TOTALLY erases your hard-drive, leaving nothing...
In this case you will need a setupcd before you can continue. I don't know of any ****-removal tool called killdisk and anuhow you should really always be careful when using any program called kill anything...
Sorry I can't help more with the info you gave.
Cheers,
Petri from Finland
