I used to mock my friends who used windows saying that they wasted 40% of their time watching the clock cursor and another 10% fighting with the blue screen of death. While I am a proud mac user, I have seen macs freeze, very rare and extremely unfortunate though. I use backup programs, which connect my mac to my online world, ensuring my data is very safe, even in case of a theft or a crash. You may still need to recover files in case of a disaster. Macs never freeze, but if it does, you can make use of very good recovery programs. You might want to Recover Mac files, when you lose sets of photos from your vacation. Using Disk Doctors, you can easily achieve your goals and also work smart with a intuitive software. There is also a free demo, which you may want to try before signing up for the $49 Photo Recovery Mac software.
Like always, since macs and ipods work in arms, you may want to extend this software to receover files on your ipod as well. All your music, videos and photos on your ipod can be recovered using Recover iPod software.
