Formatting Procedures for CF Memory Cards
For the Cisco MWR 1941-DC router, Cisco recommends that you format/erase new CF memory cards
to initialize them with a Class C Flash file system. This ensures proper formatting and enables the ROM
monitor to recognize and boot the Flash.
The Class C Flash file system is similar to the standard DOS file system; however, a CF memory card
formatted with the standard DOS file system does not support booting from the ROM monitor.
Formatting CF Memory as a DOS File System
To format a new external CF memory card, or to remove the files from a previously installed external CF
memory card, enter the
format slot0:
command.
The following example shows output for formatting a CF memory card formatted with a Class C Flash
file system:
Router#

Format operation may take a while. Continue? [confirm]
Format operation will destroy all data in "slot0:". Continue? [confirm]
