1. A method for writing or otherwise changing data in a non-volatile storage device supported by a block device driver so as to provide ruggedized operation, the method comprising the steps of:

  • a. sending a command to the device driver for defining current data contents of the storage device as a fall-back state in case of failure;

    b. sending a sequence of one or more commands to the device driver, each command potentially changing the data contents of the device; and

    c. sending a command to the device driver for defining the resulting data contents of the storage device as a new fall-back state in case of failure.
