I had a problem downloading the apple i-tunes software. While reversing a change I made I managed to locked myself out of the system. In desperation I did a disk recovery, at lease I thought it was. My understanding was that the system would be like it was when we first purchased it. However, after the restoration I still had my accounting software and data, along with the I-tunes application. However all songs are gone in addition to my docs. I knew this would happen but I was desperate to get the computer running again. Any way to get any of the songs back? Is it possible for an expert to recover them? I hear about information being recovered, how about in this case?
