Convert MP3 player to Portable Harddisk

I bought a Samsung (YH-925) 20Gb harddisk a couple of years ago. It was a rubbish mp3 player and i’m sorta glad it broke because it meant i was able to buy a new, decent one.

anyway, i don’t want to waste the harddisk so was wondering if i can format it in some way and install drivers on it that will allow me to transfer photo’s from my camera to it, when i’m in the field.
