I purchased an 11" MBA with 64G. I purchased the 240G Mercury Aura Pro 2012 6G SSD. The process for swapping the SSD is very straightforward, but when I opened the OS X disk utility via internet recovery, the SSD was not recognized. I tried fdisk via terminal, but the only drive recognized is disk0, the OSX image, 1.2G. I reseated several times, performed PRAM reset at the suggestion of OWC tech. Cleaned the contacts with an eraser and alcohol at the request of OWC, and eventually returned the drive for replacement. The replacement drive, sadly, had the same issue. I WANT THIS TO WORK! I doubt I'm so unlucky as to get two bad SSDs in a row. Has anyone had success or failure with these drives on this particular machine? Thanks!
