hi,

just finished putting my new parts together.
i succesfully booted my old HDD (which is the only think i kept from my old system) from the windows 7 CD to format it and install win 7.
my question is: is this the best way to clean the HDD? i dont know if i remember correctly that there is a better method.


thx <3
