Using the Flash Disk

OL-6452-04

Working with a Flash Disk

Using the cd Command

To move back and forth between installed Flash Disks, use the cd command by defining a specific path

name. Then to verify your working directory, use the pwd command:

System# cd disk1:

System# pwd

disk1:/

System# cd disk0:

System# pwd

disk0:/

You can also move up (or back) one level in the Flash Disk directory hierarchy using the cd .. command,

and then verify your working directory with the pwd command:

System# pwd

disk1:daily_dir/

System# cd ..

System# pwd

disk1:/

System#

Using the dir Command

To list the directory structure and contents of the Flash Disk from which you are currently working, use

the dir command with no arguments:

System# dir

Directory of disk1:/

1 drw- 0 Jul 25 1998 10:23:11 daily_dir

2 drw- 0 Jul 25 1998 10:28:37 access_lists

48755200 bytes total (48742912 bytes free)

System#

Note that the size of the Flash Disk is shown in the output of the dir command. (A 48-MB Flash Disk is

shown in this example.) You can also view the contents of other directories and file systems using

specific optional arguments with the dir command. (See Table 4.)

Using the format Command

To format a new Flash Disk, use the format [disk0: | disk1:] command.

Note You must format a new Flash Disk before you can use it. If you plan to use a Flash Disk that was

formatted and used on another type of system, see the “Compatibility Requirements” section on page 4

to determine if you need to reformat the Flash Disk first.

Caution The formatting procedure erases all information on the Flash Disk. To prevent the loss of important data

that might be stored on a Flash Disk, proceed carefully. If you want to save data that is currently on your

Flash Disk, copy the data to a TFTP server or to another Flash Disk before you format the new Flash

Disk. A Flash Disk that was shipped as part of a configured system contains a Flash Disk-compatible

Cisco IOS software image; therefore, you do not need to format it to use it in the system in which it was

shipped.
