To test a card, insert the card and enter:
enable cflash test start=startnumber end=endnumber
where startnumber and endnumber are positive integers within a cluster range.
The endnumber must be higher than the startnumber. Cluster ranges are
displayed in the output of the show cflash test command (Figure 1-13 on

sectors. Sectors can be tested as single sectors or as a range. The test will consist
of a write/read/verify cycle.
To stop the test, use the command:
disable cflash test
To display the testing process while a test is in process, enter:
show cflash test
