My phone(Samsung Epic 4G) just went dead and when i powered it back on i keep getting an icon in the notifications that says sd blank or unsupported file system when just before it was reading it with everything on it.

Can u Please suggest How to fix this sd card blank or unsupported filesystem error as i had done Odin and formatted my sd card number of times also. I tried with different SD cards and New SD card also.

So someone please help me on this in finding a solution for this.
