hey guys, so i was walking around a flea market and i pass by this guy. he is selling random electronics. i come across this 80GB internal harddrive. he said it was from an older mac or something? he wasn't sure. and it was only $20. so i was like hey, $20 is cheap for 80gb. i could use it as an extra harddrive for my mac (external). however, when i tried connecting it. i couldn't reformat it. i can boot it up. and it takes me to the original guys login screen. so i just try a password re-set but it doesn't work?? (with my tiger os install disks) it's FIRMWARE LOCKED. what does that even mean? i can't even re-format it. any idea's? i'm almost positive that this guy just stole the latptop and decided to part it out? or something? i went back to try to get it resolved... lets just say that went no where. anyhelp would be great. thanks. also, mods, i wasn't sure which category this would go under. move it if you'd like. thanks.
