Ok, so my friend was messing around on his mac mini and got the bright idea to turn FileVault on, well it takes a little time to do this so he left his computer on and turned the monitor off. His dad decided he wanted to use my friends Mac because its better then the family PC and hit the power button thinking the computer was off when it was really the just the monitor. Now the image is corrupted from what he's told me and he doesn't know of any way to get his data unencrypted or uncorrupted. He has a lot of work on his Mac mini, such as home movies and video production work he had did when were in highschool. Is there any way to unencrypt or uncorrupt or save his data?
