Hi,
Trowing away your (even defective) motherboard is like trowing away the key of your house. Without the key, you won't get in. To get in without a key, you will need some information about how the lock works so that you know the backdoors that exist to unlock it.
Those making the locks will not easily give you this information, since when it is widely spread, the lock uses it's function. (Only allowing those in with the key)
In case of HDD's, the lock pasword is somewhere stored on the system area of the disk. So, the major problem is to find the way to access and alter the information on that area. The way to do this will probably differ from brand to brand, and might even differ between different models.
Once you found your way in there, you could compare the information between a locked and a unlocked drive to see where it differs. The manufactures still can make it hard to find the correct information, as they can encrypt it with a DES algoritm so that the information of one drive can't be used on another.
You could try to do a bit of reverse engineering, for instance with a datalogger on the ata port of a drive. You could then run the unlock program and analyse the information that passes on the ata port. It will probably take a long time to analyse this information, and probably, it will only work for one brand of drive.
You might think that I am a doomthinking person that forgot to take his antidepressiva, but believe me, I have done some reverse engineering in the past, and the story is less bright then they wan't you to believe in movies when they do some hacking work.
Basically, the tools exist to unlock the xbox stock drives. If you put a larger disk in, you either don't have to lock it at all because you have a modchip, or you softmodded it and locked it afterwards, so you should know the key to lock it. Writing it on the disk is a good practice. Don't you have a spare key of your frontdoor somewhere around in case you loose yours?
I can understand you are a bit pissed you had to pay for just a code to use your disk again. But, their price is reasonable, and a second time, you will probably know your HDDKEY and won't need them anymore.
So, if they say on their website that it took a long time to develop the tools, I believe them. (Trust me, I don't work for them.)
Basically, what I am trying to explain is that, although what you are supposing probably is possible, you better might put your energy in something else, maybe more usefull. Unless of cause, you have already some of the critical information needed to work on.
regards.
