My cousine tried to fix a broken harddrive in her MacBook. She accidently overstretched the cable and the wires broke. So she asked me how to fix it.
It was quite easy to repair. You have to be very careful not to damage the cabel again. But it all went well and now she got a MacBook with multiboot SnowLeopard and Ubuntu ;)
Advice! PLEASE iFixit.com! You have to put a bill onto the outside of your parcells. The german customs didnt allowed the parcell to be shiped to me. I had to fetch it from the customs, because there was no bill on the outside!
