Give it a try sometime. Its a great way to brick a hitachi drive.
Thanks for the information, I will go against your advice and not try it sometime, as I'd rather not brick a working hitachi pcb.
I'm glad you replied, because If it was a Hitachi drive I would have been screwed, well, in the situation I was in, It was already a RGH to get Osig situation anyway, so no loss, but I admire your reply of making my success story seem like a noobish waste of time and making it worthless, I hope it makes you feel better about yourself though. I'm sorry it is something that is not documented but worked for me, but that's the way it happened, just posting my experience as it may help others in the same situation.
Are there any other deadly commands I should know about you could please post here?
