I am trying to identify the correct flash file system for a 3662 router. I believe it uses a Class B File System but am not 100% sure.
I have to install some new flash in a 3662 and wanted to clarify whether this needs formatting. Sometime ago I had to do the same for a 3640 which I upgraded but I cannot remember how I did it.
Has anyone done this lately. If so could you please explain how I format the flash.
