// Only in Armv5 platform,
// C: Drive is set to be monitored using KApaDrivesToMonitor. The value of 
// KApaDrivesToMonitor is set to 4. It is computed in the following way.

   @SYMTestCaseDesc Test for the drive's notification.
   
   @SYMTestPriority High 
  
   @SYMTestStatus 	Implemented
   
   @SYMTestActions 	In armv5 platform, the patchable constant KApaDrivesToMonitor is set to monitor C: drive. 
   Hence the notifications from other drives are ignored. The test copies the tnotifydrivesapp_reg.rsc to either 
   D: or E: drive and also to C:. There will be no notification from D: or E: drives and the applist wont be 
   updated whereas from C: notifications will be issued and applist will be updated.
   In Winscw platform, all the drives will be monitored by default and notifications will be issued when the test
   copies tnotifydrivesapp_reg.rsc to C: drive and W: drive and the applist will be updated.
   
   @SYMTestExpectedResults The app is not added to the applist when no notification is issued and applist is 
   updated when notifications are issued.
