If you really want to destroy data beyond recovery,then its time to crank up the oven temp.None of the supposed wiping tools will make it impossible.If you simply format and reinstall windows,thats as good as it can be.
Programmes like Norton SpeedDisk have an option to wipe the free space on a disk, but as others have said "if someone is determined to extract data from your drive after it has been 'erased', it can be done!" Even fdisk can be reversed by the use of a programme called MBRWorks. Formatting can be reversed with UnFormat from Norton.
What is important here is "if someone is determined enough". Usually deleting the data, emptying the recycle bin, defragmenting and wiping the free space will be sufficient to hide your information from most people.
