/**
Instructions:

This is a manual test created to verify DEFXXXXX, 2 executables needs to be run to do this test
1) t_sqlfilesrvcrash1.exe - Generate a corrupted journal file, this will cause the device to reset. 
2) t_sqlfilesrvcrash2.exe - After the reboot, tests if SQL can handle the courrpted journal file.

This test requires a non-rugged drive to store the database file and therefore will only work in hardware mode

@SYMTestCaseDesc        Tests for DEF144027: SQL Open returns error if the reported and actual file size are different
                        This function creates a corrupted jorunal file on a non-rugged FAT, where the actual and 
                        reported file size is different. This is done by killing the file server forcing the device to 
                        reset. After the reset t_sqlfilesrvcrash2.exe is used to verify SQL can handle this corrupted
                        journal file properly.
