I can't mount my hard drive on my iBook 500mhz. This has happened before but I was always able to repair it by running disk utility and repairing the hard disk. This time it isn't working. It keeps saying to try to run repair again...I ran repair many times, but i keep getting the same msg. What can I do? I really don't want to bring it in for service, is there another alternative? I have files in the hard drive that are important too....so i can't just reformat it!! Any help will be appreciated. Thanks.
