The internal HDD in my white MacBook is broken. I have a spare Toshiba laptop HDD which I plan to install in the MacBook but when I compare the broken MacBook HDD (Hitachi brand) and the Toshiba HDD side by side I see that there is an extra set of pins on the Toshiba.
The corresponding place on the Hitachi HDD is empty so I am a bit scared that when I push the Toshiba HDD in the pins may be deformed. Do you suggest using the HDD?
The extra pins I refer to can be seen on the rightmost side in the picture below:
