My 20GB iPod is having the problem where when you turn it on it displays the file folder and exclamation point and someone I know from school told me it's a corrupt file and I need to clean off my iPod and put all my songs back on to correct it.
No form of the reset does anything and neither does anything from Apple's troubleshooting pages

.
When the iPod is not plugged in, it randomly switches between a blank screen, the apple, and the folder/exclamation point.

It doesn't matter what buttons you push, it simply does one of the two things above.
All forms of resetting I've read from the troubleshooting pages have not allowed my computer to read my iPod.
Any help would be greatly appreciated. Thanks
