A format, then reraise windows and then reformat with different partitions will get rid of any and all data on a disk. BTW, it's still possible, although somewhat hard, to get the data back at this point, unless you're actively using the drive. Me and my friend managed to retrieve 8 years old information from a 510 MB drive in about a half an hour of work. All it takes is time, take it to someone who you know can do stuff with PCs and ask him if he's able to retrieve data.
