Formatting Procedures for Compact Flash Memory Cards

The following sections describe formatting procedures for internal and external compact flash memory cards.

Formatting Procedures

We recommend that you erase (Class B) or format (Class C) new compact flash memory cards to initialize them with either a Class B or Class C flash file system. This ensures proper formatting and enables the ROM monitor to recognize and boot the flash.

Note A compact flash memory card formatted with the standard DOS file system does not support booting from the ROM monitor.

Determining the File System on a Compact Flash Memory Card

To determine the file system of an external compact flash memory card, enter the show slot0: all command. To determine the file system of an internal compact flash memory card, enter the show flash: all command.

•If geometry and format information is not displayed, the card is formatted with a Class B flash file system.

•If geometry and format information is displayed, the card is formatted with a Class C flash file system.
