I think this may have happened to my MacBook Air 62 GB (Summer 2012). One day I booted up and nothing happened, just had a blank screen that never went away. I tried to use the internet restore and it couldn't find a drive. I then USB booted to Ubuntu and looked for the drive, but no drives were there.
Does this sound like the drive failure they're talking about? It happened a month ago and I haven't touched it since. I obviously can't run the firmware test they suggest, because my drive has already seemingly failed.
Sounds like it. I'd be taking it in anyway, even if you're slightly out of warranty, most Apple Stores are happy to waive the cost if you have had any specific suffering due to it.
Same thing happened to me around the same time. I went in reporting failures and not being able to boot into it or find it with liveboot. Genius recommended a reformat which somehow installed (but didn't really work, console all also reported failures).
Second visit ended up replacing the hdd with a new one. Just did this update and my Mac isn't doing so well. user land can't load. Beware.
EDIT: Eventually it came to life, my model is TS064E which is apparently one of the effected models, so it looks like a third Genius appointment for me.
Happened to me a couple of months ago. MacBook Air Summer 2012. One day, it would no longer turn on. Took it to Apple Store and was unable to find the disk. They replaced the drive and put the OS on it for me.
Same thing happened to me in September. Fortunately I had backups so no data was lost but I was out a computer for a week and had to shell out $300 for the repair.
I spoke to Apple this morning and they issued a full refund.
There were reports about failing toshiba ssds in macbook airs before. My SSD too died. Got it replaced in 1 day (EU 2 year warranty) by an apple reseller
