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
