Apple has announced a ‘MacBook Air Flash Storage Replacement Program‘ for ALL MBA systems purchased between June 2012 and June 2013.  The program speaks specifically to flash storage replacement and ONLY affects 64GB and 128GB MBAs containing Toshiba SSDs.  The SSDs are being replaced as a result of the potential SSD failing during future use.

  

　　The specific models of the SSDs are TS064E and TS128E and MBA owners are advised NOT to install any operating system updates or applications and to backup data on a regular basis until the repacement is received.  To determine if your system is affected, go to the Mac App Store, click on updates and choose MacBook Air Flash Storage Update 1.1 which will determine if your SSD is affected.
