The firmware for my MP3 player has got corrupted due to damaged computer-mp3 palyer connection wire!!!!
the result is that when i click the mp3 player icon in MY COMPUTER window,the message is displayed that THE DISK IS NO FORMATTED.YOU HAVE TO FORMAT THE DISK.
When I click YES,then the message is displayed that TEH DISK CANT BE FORMATTED!!!!
I clicked on the PROPERTIES of the MP3 PALYER DISK,it is showing 0 BYTES..However my MP3 player is of 1 GB!!!!
The same thing happened when I first bought the MP3 player,so I took my player to the shop and he installed some softwarre in it due to which my mp3 player became ok and it started showing the right memory(1GB)!!!!
so plz guide me in this regard!!!!
I have tried some softtware from net but not working!!!
