Disk error! everytime i try and go into my music file or any other file,other then radio,the sreen shows disk error.Why is this and what can I do to resolve this?

1) Disconnect from computer, turn it off, hold in volume + button and reconnect it to your computer - continue holding volume + until the Found Hardware Wizard comes up.

2)
REFORMAT FOR WINDOWS MEDIA PLAYER - Erases Everything: Connect your iLo player to the computer and open Windows Media Player. Click on the Sync tab. Pull down the drop down menu underneath the Sync tab by moving your cursor over the Sync tab and left clicking on the little black arrow underneath the Sync tab. Highlight "ILO 2GB" (wording may vary slightly), and then select "Format." - this should erase everything, and give you a fresh start.
