Hi, Recently, I reformatted my 24" iMac. I haven't turned it off since, and just a few minutes ago, it lost power accidentally and turned off. When I turned it back on, it looks like most of the settings I changed, (size of the dock, backgrounds, and folder name changes) were back to their default settings. When I went to go rename my folders back to what I wanted, it says the name is already taken. Also, all the things I downloaded are gone, but I think they are still here somewhere because it says I have less Gigs than I would have if they were really gone. Is there any way to fix this or do I have to reformat my computer again. Thanks!
