You can again use ExpressCard accessories by replacing a faulty ExpressCard cage.






Before start, make a clone of your old HD into the new one, if you don't want to initiate a fresh copy. (Carbon Copy software is good).
What is this about removing the PRAM battery causing a reinitializatio n of the HDD? For serious?
Wait, I misunderstood you. I thought the comment was directed at the PRAM battery removal page. Silly me.
Nevermind. Yes, it is always a good idea to backup one's data before doing stuff like this. I never do, and have never had any problems, but it's still a good idea.
The two screws removed in step 3 should not be mixed with screws in steps 5 through 7. Though similar, they are actually slightly shorter and have a bigger head. If you put the longer screws back in here when reassembling, the button to unlatch the top will not work properly.
