Wow, i dont know where to start.. I have a iMac 27" intel i7 2011. Havent had any problem with it until yesterday. I was erasing my files i had in my recycle bin and for some strange reason i see that around 70% of all my files on my harddrive was gone. I also saw in finder that i had almost entire harddrive empty.. Hmm, i was scared but i thought that this is not so bad, because i have a 2TB external disk that's making time machine backups all the time. I booted up with my recovery parition and started to recovery from time machine backup that i have since a few days ago (to be sure that it worked then). When the recovery was finished (after around 8h / 600 GB) it was complete. But now when im booting up my iMac, all i got is apple logo and spinning wheel. I can hear that all my drives is starting up, exactly like always, but its stuck there, its spinning.. What i've tried until now is: - Repair disk permissions - Repair disk - Resetting NVRAM and PRAM - Disconnect all cables and only run with power cable connected. - Safeboot (Its the same here, cant boot) - Doing another time machine recovery but at a even earlier date. Please guys, help me EDIT: I had not been able to boot at all since a did my first try to recover from time machine.
