Macbook Air 2012 do not load, SSD problems and could not restore data
OS X Mountain Lion
Yesterday all was OK until I open simple website (without virus, because it is localhost website development).
My Macbook Air halts to few seconds and reboot.
Then on evening it worked well.
I had plug in its power and close it.
Morning I opened macbook and it begins to load (yesterday I did not shutdown it).
It shows gray screen, apple logo and for 1 second it shows progress bar. Then ajax-indicator-loading-star appears for less than second and macbook switches off.
And it is repeats - I switch it on then it switches off.
I tried to reset pram - not works.
I tried to make test (ALT+D on load) - test halts forever after 40 minutes of testing (touchpad stop work).
I tried recovery mode to backup files (ALT+boot) - Recovery panel say that I must to repair HDD. When I try to repair HDD it says I must to backup all files. I bought USB HDD drive 500Gb, formatted it to appropriate file system and try to restore Macintosh HDD to this drive - Recovery tool says it was a problem to backup (no verbose message).
I have not TimeCapsule to backup my data.
I have very important data on SSD.
How to restore it?
