I/O Device Error

Hey, I have a Samsung Yepp YP-T5 digital audio player. It's a little mp3 player that I have. One time I accidentally press something on the mp3 player...I wasn't really sure becuase it was in my pocket and I was leaning against something. Maybe I formatted it or something, I wasn't sure what did I pressed and I couldn't play anymore songs. So I went home and I tried to put back songs on it but the problem is when I plugged it into my PC, and I double click the REMOVABLE DISK icon, it would have a pop up saying I/O Device Error...And my mp3 player would say No Files. Can anyone help me to fix this?

have you already contacted the producing firm of your player?

my mp3 player did that....i couldnt ever use it again..i guess when you accidently formatted it, it faulty'd the hard drivein the mp3 causing it to have a I/O device error...its kinda like extracting files from an external hard drive to ur computer and then suddenly pulling the plug out while its transferring....same sort of thing...if you can, try formatting it again while its in the USB slot...if u cant...then it might not be able to be fixed.
