If you owned an enterprise and you managed the PCs would you not want to assume the responsability?
Of course you would! You want absolut assurance hat only your IT staff can fry the drive. So you will need a server tool that gives you total authority over these events. And only you!
An other question: What does the client side ETS/ETDM do? Can you use the client side ETDM to remotely fry the drive?
