WARNING: If the Apple Store replaces your drive, it owns the old one

I have had many great experiences at the Apple Store with the Genius Bar. They have helped me repair multiple Macs which were beyond my own ablities to fix, despite a good collection of diagnostic and drive repair software. But it is important to be aware of some policies which may be to your disadvantage as a consumer. Specifically, if you bring your Mac to Apple and they replace the hard drive, Apple now owns the drive. i.e. You can't have it back, and there is no guarantee that the drive might not be reused by someone else capable of snooping around your data.
