I've had a hard drive failure on my Mac Pro this week. I'm somewhat flummoxed by reading Apple's TOS from Apple Care. You can exchange parts, but they get to keep the old damaged part. In this case my OEM hard drive supplied by Apple, a Seagate 160GB. I didn't have a chance to zero it out and remove my data before the hard drive failed. Do the Apple stores destroy the old drives, or are they subject to tinkering with the techs in the back room? Has anyone had any experience with the Apple store on hard drive replacements? Otherwise I think I'll just be happy to spend $44 at Amazon for a new hard drive and keep my private data private. Thanks in advance.
