Beware of the innocent
hey, let us get the question clear ok. He needs to take and give out the harddrive to his cousin. So no bios changes will persist. And changing the jumper settings or setting the harddrive to slave and all is just a matter for noobs. If a guy can install a harddrive in his sys, he will know how to set a harddrive as a master or whatever. (Not that it will matter anyway). What this guy seems to be asking is if he can make the hardware fail temporarily and any such changes can only be done on the harddrive. The only answer which came even near this problem was by @siriusb.
