Abstract: A method of managing a rewritable mass memory subdivided into sectors within which data pages are recorded, and data periodically updated, where data erasure in a sector erases all previously written data therein. The method includes: writing pieces of data in a sector, each piece being associated with a first block containing at least one information for identifying the data piece, writing information data in an administrative block for managing the data of the sector concerned in the sector, each block being written among other data of the sector and being associated with a second block including one information piece and one check information piece, a block including a first part giving general indications and a second part including a counter being incremented at each writing of an administrative block in a new sector, each first block including a check number which is based on the corresponding administrative block counter.
