Hello Everybody,
I have just had the same problem :-( and I would like to know:
1) If it is possible -safely enough- to unplug the SATA connector from the mainboard side; some say no, but further expert advice is always welcome;
2) If it is still possible to find and buy a working sata cable for the Time Capsule A1470, don’t mind if it’s second hand.
Thank You Everybody
(and thank you Apple for making your products so easy….to repair, I was just succeeding in replacing the broken fan, when the HDD went the wrong way when I tried to reinserting it)
