I have a one year old iBook whose hard drive crashed completely. Tech support at my work says it's impossible to recover anything off of it, and they want to send it off for a replacement. I asked about those recovery service companies and the tech people told me they don't really work, that you end up paying thousands to recover your lost data with no guarantee they'll really get anything. Is this true? I'm sick over the loss of my photos and music, which weren't backed up...
