Hi, Was trying to make my hard drive be able to play on the ps3 so opened disk utility and changed it to MS-DOS FAT didnt realise it would delete everything and then put it back to Mac OS Extended (Journalised). Is there any free way to get my files back please? It's got all of my uni work on it and I'm totally gutted about losing everything. I did try pressing repair and it said "Error: Could not unmount disk". Hope someone can help!
