Fistly, I connect my player to PC with USB cable
I see following screen
Then I use MP3 Player Disk Manager, and format -full / low mode
Afther than, I format in windows with FAT mode (because I tried fat32 then windows give me error message "Windows was unable complete the format)
Then open removable disk drive window as fallows
when I tried delete this strange files, then windows give following message
Then I tried MP3 Player Upgrade Tool (fw:9.0.43 to fw:9.0.51)
My player also give "disk error" message. I cutting usb connection and reconnect, then I back to the firs step, windows wants to format.
Where I was wrong ? How I'm cutting this cyclic process?
