A locked block in Flash memory cards occurs when power is lost or a Flash
memory card is removed from its PCMCIA slot on the RP during a write or erase
operation.
When a block of Flash memory is locked, it cannot be written to, or erased. Any
attempt at such an operation will consistently fail at the blocked location. The
only way to recover from locked blocks in a Flash memory card is to reformat the
Flash memory card using the format command.
Formatting a Flash memory card erases all existing data on the card.
The modular configuration and modular command reference publications in the
Cisco IOS software configuration documentation set that corresponds to the Cisco
IOS software release installed on your Cisco hardware. You can also see the Cisco
IOS software release notes for the version of Cisco IOS software you are using on
your router.
