If You Need More Information

Locked Blocks in Flash Memory Cards

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 to do so will consistently fail at the block 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.

Caution Formatting a Flash memory card erases all existing data on the card.
