Testing a CompactFlash card
To display information about the basic state of a CompactFlash card, including
card size, file count and serial number, insert the card and enter the command:
show cflash
To display cluster ranges on a card, insert the card and enter the command:
show cflash test
The following figure is an example of output from the show cflash test
command when no test is running.
To test a card, insert the card and enter the command:
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.
The test software will read the file allocation table and display a list of free
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 test status while a test is in progress, use the command:
show cflash test
The following is example output from the show cflash test command when a
test is running.
Error messages are displayed when a file write fails. Failure could be due to the
card being removed or an error in the card.
