So earlier this year I suffered a critical blow when my launch day PS3 finally kicked the bucket and gave me the dreaded Yellow Light Of Death, as sad as this was I was also slightly excited as it meant I would now have an excuse to upgrade (or side..grade, whatever) to the PS3 Slim.  
 
When I got my Slim I rushed straight into playing on it and now, 2 months later I have built up a pretty decent amount of saves and data on that system.  
 
Now, I've finally decided I'd like to finish / go back to some of the stuff I played on my old PS3, but how can I access the data? 
 
I assumed I would simply be able to exchange the hard drives, copy the files I wanted to an external hard drive and then paste them back over the the slims hard drive, keeping all my awesome data and progress in one place. From what I've read though, inserting a new hard drive into a PS3 will cause it to format the drive, losing all data.  
 
I then read about using an ethernet cable from PS3 to PS3 slim to take the data but AGAIN it will wipe all the data off the receiving hard drive and I doubt that would even work with a PS3 suffering from YLOD.  
 
So here is were I need the great and nerdy minds of the giant bomb community to help me.  
 
Is there anyway for me to access the data on my old PS3, take the files I want from it and paste those files onto my new hard drive? Or am I just going to have to say good bye to my 95% completion on Just Cause 2 (e.t.c) D: 
 
Thanks for the help!
