If an error occurs during a write of more than one sector, writing terminates at the sector where the error occurs.

Write Sector(s) without Erase

This command is similar to the Write Sector(s) command with the exception that an implied erase before write

operation is not performed. This command has the same protocol as the Write Sector(s) command. The sectors

should be pre-erased with the Erase Sector(s) command before this command is issued. If the sector is not pre-

erased with the Erase Sector(s) command, a normal write sector operation will occur.
