MacBook Air SSD Failure?
MacBook Air A1370 froze on an application so reset it by holding down the power button.
Now it shows the folder with a question mark icon - OS cannot be found. It can't find the recovery partition (command + r) and when booting from a Mac OS X USB install the installer is unable to find the SSD.
When opening it up in system profiler (when Mac OS X installed on a external drive) the SSD appears as an unknown device on the NVIDIA bus.
Unfortunately I was travelling at the time and didn't backup a few files which I require. Any other ideas aside from taking it into DriveSavers? A local tech has had a look at the SSD and it appears to be OK from a visual inspection.
