I have a friend who's hard drive died on their Mac Mini. I have removed the hard drive and placed it in external drive enclosure. I have a trick that may give me 5-10 good minutes with the drive before it spins it last spin, and I intend to use that time (if I can) to get a few files from the drive.
After talking with the friend, the most important data to them are photos that were stored in iPhotos in one of the profiles. Given that I will have at best only a few minutes with the drive, I want to know exactly where on the file system to look for this data.
