Step1: Format and open the media; 
Step2: Enable fault tolerant feature;      
Step3: Create new file called "TEST.TXT";      
Step4: Check the media available bytes;
Step5: Write 1500 bytes to "TEST.TXT"(two clusters);
Step6: Check the media available bytes;
Step7: Loop to write random size bytes to "TEST.TXT"(less than two clusters); 
Step8: Check the media available bytes every write operation.
