i am looking for testing and formating hdd
software

you're going to have to be more specific, what do you mean testing? and why do you need an app to format?

Window's scandisk will test drive for as much as you need at present...and it will also take care of formatting, and fdisking. As William said, what are you up to?
A good google search will turn up whatever you need.
