Abstract
In a particular embodiment, a controller is disclosed that is adapted to control read/write access to a storage media. The controller includes data corruption detection logic to reconstruct a logical block address (LBA) lookup table from metadata stored at the storage media upon restart and re-initialization after a power loss event. The controller further includes duplicate conflict resolution logic to identify a valid data block from multiple data blocks that refer to a single LBA. The duplicate conflict resolution logic counts a first number of valid physical pages and a second number of different sectors in each of the multiple data blocks. The duplicate conflict resolution logic selects the valid data block from the multiple data blocks based on at least one of the first and second numbers.
