original xbox hdd re-useable?

[fiNgA]

if i wanna use my original xbox hdd in a pc, how do i get it to format? do i need to put it back in my xbox and 'unlock' it, then move it to the pc and do it from a windows xp disk? or is there a way of getting it to format without unscrewing my xbox again?

really wanna use it in a spare pc, have its original contents backed up on another pc
