The method involves checking a flag memory for each address conversion in connection with a sector write command leading to a written sector to determine if the given block address is present. If not the contents of the sectors of the relevant blocks are written to unwritten sectors of blocks assigned according to the flag memory contents. The method involves, following each address conversion in an alternative memory block address, storing it with the associated sector address assigned to the logical block address in a flag memory (MS). The flag memory is checked for each address conversion in connection with a sector write command leading to a written sector to determine if the same block address is present. If not the contents of the sectors of the relevant blocks are written to unwritten sectors of blocks assigned according to the flag memory contents
