I think the op may be the same user who was going to rgh with that hard drive that didn't work due to being on official firmware. if you can get a wd scorpio make/model, it will work. then you can plug it into your pc with the transfer cable to use with fatxplorer. I've done this before, and it should work. 500GB seems to be its limit though as I've heard of instability with larger hdds. you can get your saves on there, which I think are 00000001 folders iirc. you may have to resign them, but it's been a very long time for me. you can use use memory cards as I think there's a pc reader for them of some sort. I don't know if a slim has memory card ports, but iirc, you have a phat, right? I have two memory cards in mine. I think 512MBs is the largest. I have like a 512 and a 256, just to have. I think I put my profile on them for storage, but it's also on the internal hdd. I don't know if you can get anything to read an external hdd that's been formatted by the system. I don't think you can access that data even with a jtag/rgh. it seems to be encrypted in some way.
