mfsReadDiskID


Format:	s32 mfsReadDiskID(LEODiskID *diskID)
Arguments:	disID	LEODiskID structure buffer
Return value:Error
Function:	Reads disk ID
Description:	This function reads the disk ID and stores it in diskID.
It enables LeoReadDiskID to be handled by using the MFS library.
When the MFS library is used, using this function may cause a problem in checking whether or not the disk has been exchanged.  Therefore, mfsDiskIdCheck should be used.

Main errors:
	MFS_ERR_NO	Normal termination
	MFS_ERR_DEVICE	Device error
			An error occurred in an internally called Leo function.
Since a Leo function error is stored in the variable mfsError, check this variable to perform processing.
