Abstract
A system and method for managing the storage of data in non-volatile memory is described. In an aspect, the data may be described by metadata and a transaction log file that are checkpointed from a volatile memory into the non-volatile memory. Actions that take place between the last checkpointing of a metadata segment and log file segment are discovered by scanning the non-volatile memory blocks, taking account of a record of the highest sector in each block that is known to have been recorded. Any later transactions are discovered and used to update the recovered metadata so that the metadata correctly represents the stored data.
