This particular machine is using Windows 8.1 as primary OS on the MAC instead of OSX. While running on Windows, the warning message after login to the machine saying the disk has some issues. Boot into OSX and it confirmed that on the disk there is a warning saying: S.M.A.R.T. failing.
Here are the procedure to handle this:
- Contact Apple Support to check whether it’s still under warranty or not. Please note that in Australia, there is a consumer protection law which any device that more than $800 the warranty needs to be 2 years. Apple Global Support doesn’t know this – by default is only 1 year. Apple will advise to go to their repair centre or authorised third party.
- Boot on Windows 8.1, run System Backup first
- Apparently, there is a way to safe Bootcamp partition natively without third party software – How To Backup and Restore Boot Camp Partition on Mac HD – https://www.youtube.com/watch?v=RGsvFem5UfU . Boot into OSX, and run Disk Utility
- Once the procedure (2) and (3) are ok, then take the device to repair centre.
- In regards to getting the harddisk back, Apple has policy that to return any disks back to them for refurbishment and they will delete permanently before reusing it.
- Once the Repair Centre has completed the job to replace the disk, you can ask them to do maintenance on the old disk prior sending to Apple to make it more secure.
