You can delete all data on hard disk drive (HDD) with diskpart clean all command you can start the Command Prompt by pressing Shift + F10 keys at same time and follow the instruction to use clean all diskpart command from Command Prompt at SevenForums website. Next time open help thread at Microsoft Windows, XP, Vista, and Windows 7 for Windows OS related questions.

During OS installation process, you will be given an option to format detected drives.

you never actually empty your harddisk, you simply tell it.. all your data is disposable now overwrite whatever you want,

but you can completly delete everything during OS installation
