Implementing Additional Configuration and Maintenance Tasks
Caution The following formatting procedure erases all information on the Flash memory card or Flash disk.
To prevent the loss of important data that might be stored on a Flash memory card or Flash disk,
proceed carefully. If you want to save the data on a Flash memory card or Flash disk, copy the data
to a server before you format the card.
To format a new Flash memory card or Flash disk, follow these steps:
Note The flash card command examples presented in this publication assume the use of a standard linear
Flash memory card. If you are using an ATA Flash disk, replace any commands with either the slot0:
or slot1: command argument with a disk0: or disk1: command argument.
Step 1 After booting your router, insert the Flash memory card or Flash disk into slot 0. (Use the procedure in
the “Installing and Removing Flash Memory Card or Flash Disk in GRP” section on page 35.) If slot 0
is not available, use slot 1.
Step 2 Enter the format slot0: (or format slot1:) command as follows:
Router# format slot0:
All sectors will be erased, proceed? [confirm]
Enter volume id (up to 30 characters): NewCard
Formatting sector 1
Format device slot0 completed
Router#
Note For this example, a 20-MB Flash memory card was used. At the line “Formatting sector,” the
system counts backward from 160 to 1.
The new Flash memory card or Flash disk is now formatted and ready to use.
For complete command descriptions and configuration information, refer to the Configuration
Fundamentals Command Reference, the Configuration Fundamentals Configuration Guide, and the
Cisco 12000 Series Internet Router Flash Disk Information publications. (For information on obtaining
