USB Flash Disk Utility v2.7.0.0 :

	    1.1 Root cause and Solution:
	          In Win2K/XP, WIN32API SetFilePointer operate with offset which uses two LONG variables as parameter. 
  	          While partition size larger than 2GB, it must use both variables to reach the offset. (Because the maximum value of a LONG type is 2GB.) . 
 	          In that condition of two parameter, the first parameter will be take as ULONG type by SetFilePointer 
	          (The maximum value of a ULONG type is 4GB) .There is a bug in original format function: the second parameter is incorrect.
	          Therefore, if the first partition size is larger than 4GB, then the format of second partition will be incorrect.
