Although the new (2011) models all feature SSDs, the older models only offered those as an option. As such, even the best build machines are not free from hard drive failures, which remain as the component with highest failing component. Regardless, in case you get stuck with a non booting Macbook Air,  here’s how to recover the data: 1. First, why does this even works? Simple. OSX uses a kind of file system called “Journaled“, which is far different from FAT or NTFS, but is quite similar to ReiserFS, XFS or most UNIX file systems around. The advantage? Consistency is (almost) allways assured, even in case of a power failure, or hard drive failure. So, even if a hard drive is having problems, it’s usually capable of giving up it’s data. 2. DON’T TRY TO BOOT. If OSX fails to boot 3 times, don’t try the forth. One of the most interesting feature of a UNIX system, is the ability to boot WITHOUT WRITING to the hard drive. This allows for a failing hard drive not to do even more damage …
