[Dave K]

Just noticed this in the log today. is there any way to test the storage and determine if the device needs to be replaced?

These messages often happen right after a flash while the router is rebooting. Just ignore them, they are caused by the firmware trying to access parts that were just overwritten by the firmware flashing process.
