I think its pretty cool there is something like this on the Amiga. I know windows doesnt distribute on of these by default, unless you include fsk. But thats a pretty stupid program and its hard to operate for beginers.
In "Windows XP Pro" -> Control Panel -> Administrative Tools -> Computer Management -> Storage -> Disk Management. One can find Window’s equivalent of HDTool Box((it may not be as good) style utility.
You can fine it as "%SystemRoot%\system32\compmgmt.msc".
