Hello to all of you.
I'm very disappointed that I have to add the case of my MBA 13" to the ones with the faulty SSD drive, too. I bought it in July 2012 in Athens, Greece. About one week ago, it was suddenly frozen and non responsive. After rebooting, there was the flashing folder with the ? on it. Disk utility still could see the SSD but only as a device, not formatted or containing any data at all. I took it to the service of the Apple store that I bought it and they told me that the SSD was able to pass hardware tests and did not seem to have any problem. They claimed of a software failure blaming it on possible "not good usage" by myself, like deleting some file that I shouldn't !!!
Anyways, they told me that this malfunction was nothing to worry about, since they see that the disk has no problem. When I asked them about the cost of a possible replacement of the SSD drive, if needed, they told me that it is 883€, unless I'm willing to return the faulty one and pay around 550€ instead. Well, today (5 days later) and after having installed mac os again and various applications and restoring anything that I had in backup (the fact is that I lost a large amount of work, which was very important) the same symptoms appeared. This time, the SSD drive does not appear even as a device.
So, I wonder: is it really right for me after having made a purchase of 1500€ before one year and 3 months, to pay 883€ or 550€ now again? If this is normal and expected from my SSD, then I suppose that I am expected to replace my SSDs from now on every 1 year and 3 months. I certainly did not buy my MBA for just one year!
