Ive searched all over, and cant find a solution. I put in a new HD for the 1.2ghz iBook 12", and it wont be recognized by the computer. I tried resetting the Vram/Pram, with no success. I also made sure the hd connector is connected. When I hold down "C" to the install disc, it reads the disc, but does not detect the HD. When I do not hold down c, it takes me to a question mark/folder icon. I do not think its the new hard disk or connector or logic board, because I have read others having the problem...some say it is the firmware, and that its the OS/Installer disc that has the error...but I have no clue how to fix it.
