I am trying to erase flash on my 2811 but get the error below. I am not sure what the next step would be since I haven't seen this once before.
Thanks in advance.
Erasing the flash filesystem will remove all files! Continue? [confirm]
Current DOS File System flash card in flash: will be formatted into Low End File
System flash card! Continue? [confirm]
%Error erasing flash: (Invalid DOS media or no media in slot)
