What happens with the data on a replaced hard drive?
I had to send in my MacBook Pro because of a damage by water. As I've always got backed up my data on several time machine disks loss of data is of course not an issue. So without any further thought I've brought in the Mac to the Genius Bar and they replaced several parts, including the mainboard – with the hard drive on it.
Now I have some concerns about the data on this drive. How trusty is it that Apple destroys the board or deletes all data in an absolute secure way? Is it possible that someone might get hands on this data, which would be a desaster... ?
