/* Tests rugged fat filing system for epoc platforms. Copies \t_scn32dr3.exe to
\sys\bin\eshell.exe to enable the test to carry on after a reset.
See t_tscan for a fuller description of the tests carried out. Good idea to
disable crash debugger via \e32\inc\m32std.h. Drive to be tested is selected at
the command line. Also useful to disable beep in \e32\kpepoc\kp_ini.cpp to
avoid excessive noise.*/
