I too have one of these players, similar only advertised and labelled as 8GB, i recently killed it after recklessly trying to put 5GB of pics, music and films (what was i thinking???!) anyways i have managed to flash some firmware back onto it and it seems OK now but what i want to know now is how much memory does it really have??
It's not compatible with MP3 Disk Tools and when doing a full format (not quick) with Windows it either reports back 7.75GB or just says 'unable to complete format' I'm pretty certain the memory is hacked or defective but i'm after a tool that can check it .. any ideas?
