Ok. So here's the thing. Back in January in done a DIY fusion on a mid 2012 i7 Mac mini. Everything was working fine till a few days ago when I started getting the dreaded beach ball after it was left on overnight. Wasn't really a problem, just had to restart and all was well again, but being the perfectionist that I am thought I'd do a fresh install of everything and see if there was a specific app that was causing the problem. I decided to split the Fusion drive in case that was what was causing it but in the rush of it (I only had a few spare hours to do it in) I forgot to make a bootable drive first to reinstall OSX with. By the time I realised what I'd done it was too late. It split the drives and also formatted them into an unusable state. (Hence why I needed a bootable drive to access disk utility to format them and do an Internet recovery with). After 48 hours of pulling what hair I and left out, I gave up and took a drive to the Apple Store. This is where it gets interesting. The guy in the store hooked it up, tried to do the Internet recovery and also failed. Then done a diagnostic check and found that both drives, 256 SSD and 1tb stock drive were red. He then went on to tell me that both drives had failed. Now knowing that this happens when you split or make a fusion drive I tried to blag it that if he could just sell me a bootable drive I could sort the problem my self. As I didn't want to tell him that I'd done a DIY fusion just to be told that my warranty was void. He then proceeded to put my beloved Mac mini behind the counter and told me that it would have to be repaired. Filled in the relevant docs and said it would be free of charge as it was under warranty. Sent me a confirmation email to confirm that the drives needed replacing and it was a free repair. Now I'm wondering that when they take it apart they will realise that I've added my own drive and try and charge me or will it stay as a free repair as that is what it was put through the system as. In 3-5 days ill know the outcome but just wondered if any of u had experienced a similar scenario and what your outcome was.
