Hey guys, big time newbie when it comes to linux and have a couple of questions...

Well first off, my computer died on me a little while ago (system32 error or something) anyways I want to back up all of my music and photos onto an external hardrive before I go reinstalling windows. I was just about to purchase knoppix 6.2 and noticed there were some older versions as well. Now should I stick to a particular version that would be better suited for me just for system recovery? Or should I just go ahead and get 6.2? All I want to do is use it to back up my files and want the simplest, easy to use, and hassle free version. Thanks in advance!
