When  user  runs  Write  or  Read  command  with  4-Kbyte  LBA  SSD,  there  is  the  message 
displaying on the console to show the input limitation which must be aligned to 8 as shown in 
Figure 3-4. When the input does 

not align to 8, “Invalid input” is displayed and the operation 

is cancelled. 
 
Figure 3-5 shows the example when the input is out of the recommended range for each 
parameter. The console displays “Invalid input” and then the operation is cancelled.
