/*          
For FAT 12, 16, 32, one cluster size is 1024 bytes;
Check media full operation:          
Step1: Format and open the media; 
Step2: Enable fault tolerant feature;   
Step3: Create new file called "TEST.TXT";    
Step4: Get the media available bytes;    
Step5: Write large bytes out of the file to fill the media;
Step6: Check the media available bytes. 
Step7: Loop to read and check the file data from the media;
