First off, do you know how to spell? Are you aware of something called grammar? Erg.
Anyways, basically what you can do is go into your computer bios and try to find anything related to freezing harddrives and try to disable it. But if you can't do that, then try this:
-Have the xboxhdm disc in your computer
-Make sure your xbox harddrive is not connected to your computer
-Turn your computer on
-Press whatever button you need to to enter a menu that allows you to select what device to boot (dvd drive, harddrives, floppy drive, etc)
-While your in that menu, hook up your xbox harddrive to your computer
-Boot the xboxhdm disc
-Try to lock the drive
If that doesnt work, go try a different computer.
