Include the colon (:) when entering this command. This command checks the specified flash memory for
errors. If errors are found, the command recommends that you format the flash.
CAUTION: If you elect to format the flash, all files – including the startup configuration
file – are lost. If you do decide to format the specified flash, consider saving the running
configuration as the startup configuration after formatting the flash (use the write
memory command or copy running-config startup-config command).
