My 2009 MacBook Pro was getting slow so took it to the genius people at Apple Store. He did a diagnostics and said the system may be volume corrupted. He also said its FileVault encrypted. So he was going to once again start the Mac take data away and was going to put in a new OS. As he was trying to switch on the Mac it didn't start up, he told me that he can put in a new OS which will delete the data. As I hadn't backed up the data I told him not to do anything. Next day My Neighbour who works on computers took the hard drive out and told me that the hard drive is working and he was able see it on the test computer but couldn't find any option asking for any password to decrypt or access the hard drive. The guy told me that I should take the hard drive to the place where they retrieve data which will cost big bucks. My question is would I be able to retrieve the data from the hard drive at all.
