Abstract
The disclosed technology provides a method that reduces time to recover in storage systems. In one implementation, the method comprises entering an idle status, determining if there is an incomplete band update operation, invalidating a media scratch pad (MSP) by clearing headers responsive to determining there is no incomplete band update operation, performing a power cycle, reading an MSP header, and determining if an MSP header is valid. If a rude power cycle occurs and the MSP header is determined to be valid, an MSP is examined, and restored if required. If a safe power cycle occurs, an MSP restore operation is not required, reducing time to recover.
