Lastly, the Flash File System (FFS) can be checked to ensure that it has
successfully formatted the flash, using the command:
show file
If flash memory has been used in the past then it may already be formatted and
contain files. With erased or new flash memory that has been correctly
formatted, an 80 byte hidden system file is present. A typical display for an FFS
is shown in Figure 14.

A complete test of flash memory may also be carried out by authorised support
personnel using the router’s built-in diagnostics. See “Diagnostics” on page 60
for more information.
!
Caution The diagnostics flash memory test erases the entire flash
contents.
